Review on feasible recycling pathways and technologies of solar photovoltaic modules. The ITRPV predicts that, by 2030, the total material value recovered from PV, reach USD 450 million. Hence, methods for recycling solar modules are being developed worldwide to, environmental impact of end-of-life modules and to recover some of the value from old PV. Before going into the details of environmental impacts, brief insights on the methods used for estimating environmental impacts, both in the conventional way as well as using LCA simulation tools, are given. Growing PV panel waste presents a new environmental challenge, but also unprecedented The better knowledge of these technologies and growth on the waste amounts that could generate profitable outcomes has supported the development of the first PV recycling plants. Today, the take-back of modules is organized via a “bring-in” system [44]. It panels, or 18 GW of power-generation capacity. Environmental and occupational health issues. It was shown that recycling technologies for PV wastes are extensively explored not just on labs and pilot plants, but some are also commercially available. The heterojunction (HIT) cells are also expected to gain some space with predictions of 15% of the total market share by 2027 [7]. Moreover, currently only Europe has a strong regulatory framework in place to, support recycling, but other countries are starting to build specific frameworks related to PV. To unlock the benefits of such industries, the institutional groundwork must be laid Because of that, there should be a continuous focus on scientific evidences on the potential impacts and benefits related to the treatment of photovoltaic residues. End-of-life (EoL) management of waste PV modules requires alternative strategies than landfill, and recycling is a valid option. materials to pay for the associated costs of the steps of recycling processes [69]. As a result of the increase in the global market for PV energy, the volume of modules that reach the end of their life will grow at the same rate in the near future. Attention has been paid particularly to silver. MML and RC acknowledge the support of the Australian Government through the Australian Renewable Energy Agency (ARENA). 2012; Recycling. for recycling c-Si PV modules are based on mechanical, thermal and chemical processes. silver, tellurium and, indium) and make them available for future use [8]. Solar modules have a lifespan of up to 25–30 years [18] and so there has been limited interest in investigating the aspects of EoL so far. The absence of valuable materials plays a key role, and process costs are the main critical variables. Furthermore, the estimation of solar waste PV, its categorization, management approaches, country guidelines and recycling of waste PV panels, were mainly focused in this study. Currently, Europe is the only, modules, including c-Si and thin-film technologies as well as an overview of the global, legislation. Environmental effect is studied into various aspects. The first step is, to crush and separate the materials mechanically, ment to recover the semiconductor metals. Second, different scenarios have been formulated by varying the mix of virgin and recycled PV modules. Today, most of the EoL modules go to landfill, mainly because recycling processes for PV modules are not yet economically feasible and regulation in most countries is, With the enormous growth in the development and utilization of solar-energy resources, the proliferation of waste solar panels has become problematic. At that price, the 10–15 kg of glass in a solar module is worth about 15 Yen (approximately 0.14 US D). The results from broken PoSCs indicated the release of 43.9 mg/L of Cu and 6.6 mg/L of Pb, which are higher than the TC limits. Most countries around the world classify PV panels as general or industrial waste. Recycling of PV modules can, stances (e.g. The summary of this process is shown in, A pilot project was funded by the Japanese Government via the New Energy, Technology Development Organization (NEDO). The glass and some metals are sent to other companies for recycling and the solar cells can be turned into wafers again. The outcomes of this process are the recovery of more than 84% of, the module weight, being 90% of the glass and 95% of the semiconductor materials [44]. DePhillips and P.D. intention to consider a scheme to deal with such waste [17]. Despite their many advantages, solar photovoltaic (PV) cells used for electricity generation can have negative environmental impacts. DOI 10.1016/j.solmat.2015.05.005 Reclaim PV has teamed up with major solar module manufacturers who distribute in Australia and is refining its processes. Total collection rate for WEEE in 2014 as a percentage of the average weight of EEE put on the market in the. However, current recycling methods are mostly based on downcycling processes, this area. The market for photovoltaic (PV) electricity generation has boomed over the last decade, and its expansion is expected to continue with the development of new technologies. b ... and it is sustained to retain its world-leading position in the collection and treatment of photovoltaic module waste. As PhD students, we found it difficult to access the research we needed, so we decided to create a new Open Access publisher that levels the playing field for scientists across the world. In this study, we used a Monte Carlo uncertainty model to identify the potential economic benefits of closed‐loop recycling of EoL PV modules when recycled silicon is integrated into different stages of the PV supply chain. As a result of the increase, the volume of modules that reach the end of their life will grow at the same rate in the near future. ... At present, a universally employed recycling process for PV waste is not yet in existence. 2014; s multi-crystalline silicon (multi-Si) photovoltaic modules considering recycling, Risikovorsorge. At present, from the technical aspect, the research on solar panel recovery is facing many problems, and we need to further develop an economically feasible and non-toxic technology. the predominant technology (90% of the market) is crystalline silicon (c-Si). lead, cadmium, and selenium), recover rare materials (e.g. The falling cost of solar has made renewable energy accessible to more people than ever before and has resulted in an exponential increase in solar adoption. MODEL INSTITUTIONAL INFRASTRUCTURES FOR RECYCLING OF PHOTOVOLTAIC MODULES Sheldon J. Reaven, Paul D. Moskowitz and Vasilis Fthenakis January 1996 BIOMEDICAL AND ENVIRONMENTAL ASSESSMENT GROUP ANALYTICAL SCIENCES DIVISION DEPARTMENT OF APPLIED SCIENCE photovoltaic (PV) industry, at reasonable cost. Quantitative assessment of the environmental effects of crystalline silicon solar photovoltaic module is favored through life cycle assessment. Summary of NEDO recycling process for Si modules (pilot project). Guidelines for inclusion of results into these tables are outlined, and new entries since January 2016 are reviewed. The process begins with the removal of the cables, junction box and frame from the PV module. 2016; solar cells. The recovery of valuable materials during the recycling of PV modules can have great economical value. The outcomes of this process are the recovery of more than 84% of the module weight, being 90% of the glass and 95% of the semiconductor materials [44]. This report presents the first global projections for future PV panel waste volumes to 2050. recover the intrinsic values of the materials present in the PV modules. Higher uncertainties are obtained for the crystalline Silicon production, manufacturing, recycling, solar cell processing and module fabrication due to greater environmental impact, also the parameter causing error are high. [5] studied in detail about various physical treatments for recycling of Si and CdTe photovoltaic modules. credits) due to the potential productions of secondary raw materials have been intentionally excluded, as the focus is on the recycling process. Arvind Sharma. California, for example, has additional, threshold limits for hazardous materials classification based on the Senate Bill, rizes end-of-life PV modules as Universal Waste (facilitating easy transport). Finally, the next step for the industry and researchers is to create module designs that are “recycling-friendly” [29]. ... Today the most popular approaches to recycle solar PV panels include technical, chemical and thermal processes. Progress in Photovoltaics: Research and Applica-. During this process, the plastic components, glass and some metals are sent to other companies for recycling and the solar, turned into wafers again. However, this will not occur. Lastly for recycling, cesses aiming to generate new materials, the aim is to keep the materials intact for reuse or, direct recycling, recovering the frame, glass, tabbing and solar cells without breakages and, good condition. penetration targets: Accounting for external costs. The best approach to recycle these PV modules is by using strong acids that help in the stripping of metals [6,33, + Increase efficiency and value of Photovoltaic Solar Panel recycling, Odour emissions from wastewater biosolids limit opportunities for their re-use via land application. In this brief review, we will describe processes for refurbishing and recycling of PV silicon. 2015; material in silicon PV module recycling. Module recycling rate of over 95 percent achievable Reprocessing more cost-efficient than purchasing new wafers New possibilities for using silicon of previously unusable quality in the solar industry High-quality recycling system reinforces the image of the solar sector. The motivation, legislation and current processes were discussed and possible issues were addressed. A Review of Recycling Processes for Photovoltaic Modules, Solar Panels and Photovoltaic Materials, Beddiaf Zaidi, IntechOpen, DOI: 10.5772/intechopen.74390. Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, s Republic of China. Final Report, ENV. Recycling technologies for this type of panels have been widely increasing in recent years. The rest of the components, The EU directive [8] established recycling targets in terms of module weight and also expresses, the intention to increase the collection rates to allow the progressive recycling of more material, and less to be landfilled. Since it is expected that more than 50 000 t of PV modules will be worn out in 2015, the recycling approach has received significant attention in the last few years. A typical crystalline silicon (c-Si) PV module contains approximately 75% of the total weight is from the module surface (glass), 10% polymer (encapsulant and backsheet foil), 8% aluminum (mostly the frame), 5% silicon (solar cells), 1% copper (interconnectors) and less than 0.1% silver (contact lines) and other metals (mostly tin and lead) [33]. It is well known that the recycling of EoL PV modules has positive influences on the environmental impacts. At the end of 2016, the cumulative global PV waste reached 250,000 metric tons, while it is expected that by 2050 that figure will increase to 5.5–6 million tons [7]. Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? Most scientists around the world recognize the existence of climate change and the fact that climate change has an anthropogenic character. At the end of 2050 China is still forecast to have accumulated the greatest amount JPEA strongly recommend that industry follow the guidelines [15]. Responsibility for the views, information or advice expressed herein is not accepted by the Australian Government. After that, these small pieces are exposed to an atmosphere containing oxygen at 300°C. Also, projections of PV module material streams are also highlighted. Whereas, there is no doubt, that solar energy will play an important role in the future of world’s energy sector, the issue of solar PV waste is still obscure. However, the current waste volumes are still low, which entails economical obstacles for the development of the existing processes. Photovoltaic (PV) solar modules are designed to produce renewable and clean energy for approximately 25 years. © 2016, American Association for the Advancement of Science. + Develop a sound, This report examines different alternatives for replacing, treating, and recycling greenhouse gases. mentioned that recycling of silicon PV modules can be carried out by physical/chemical treatment or combination of both. Once all the installed capacity starts reaching EoL (within 20–30 years) they will create a significant waste problem for Japan. This study confirms that the end-of-life management of PV modules must be thoroughly studied not only to determine the feasibility of the process but also to assess the environmental and economic benefits. Silicon solar modules recycling processes. Silicon’s value is determined by its purity. Despite frequently voiced concerns about the solubility of the lead salts that make up the absorber material, several life cycle analyses have come to overall positive conclusions regarding the environmental impact of perovskite solar cell (PSC) production. Once materials can be recovered without impurities, then they will have a higher market value, which is one of the main obstacles to the growth of the PV recycling industry with the current technologies. LCA of production process reveals that Polysilicon production, Cell processing and Modules assembling have relatively higher environmental impact than processes of Industrial silicon smelting and Ingot casting and Wafer slicing. energy future. These types of PV modules can be recycled based on the methods used for electronic waste such as cathode ray tubes and batteries. With the unavailability of walking and cycling infrastructure, people are forced to use vehicles majorly powered by petrol and diesel engines, ultimately increasing the carbon emissions. The glass is cleaned and sent to recycling. Considering, 30,000 t of silicon can theoretically be recovered in 2030 [7], which is the, needed to produce approximately 45 million new modules. The cells are, electrically interconnected (with tabbing), creating a string of cells in series (60 or 72 cells are, standard numbers used) and assembled into modules to generate electricity (, A typical crystalline silicon (c-Si) PV module contains, from the module surface (glass), 10% polymer (encapsulant and backsheet foil), 8% aluminum, (mostly the frame), 5% silicon (solar cells), 1% copper (interconnectors) and less than 0.1%, silver (contact lines) and other metals (mostly tin and lead) [33]. Considering a polysilicon current prices at USD 20/kg and a recovery rate from commercial recycling processes of 70% this is equivalent to USD 380 million [7]. CIGS has a very high optical, absorption coefficient because it is a direct band gap material, 2.4 eV by varying the In/Ga and Se/S ratios [39]) and efficiency of approximately 15.7, for high bandgap [40]. Purpose Licensee IntechOpen. For CdTe thin film modules, the results confirm the environmental benefit when recycling of glass cullet and copper is considered. NPV/size varies from −1.19 €/kg to −0.50 €/kg. Summary of SolarWorld recycling process for Si modules [44]. The non-inclusion of PV residues in waste legislation in some countries is due to different, reasons. In Japan, the scrap glass can be sold for 0.5–1 Yen/kg. distribution, and reproduction in any medium, provided the original work is properly cited. [20] Weckend S, Wade A, Heath G. End-of-Life Management Solar Photovoltaic Panels. Over the past few decades, humanity has faced a growing number of unpredictable natural disasters. of waste but Germany is overtaken by the United States of America (US). This chapter is distributed under the terms of the Creative. This method can recreate about 90% of glass and almost 95% of semiconductors, which can be used again in the production of solar PV panels. NPV/size is equal to −0.84 €/kg in a baseline scenario. A pilot project was funded by the Japanese Government via the New Energy and Industrial Technology Development Organization (NEDO). Also, manufacturers, importers and distributors of photovoltaic modules have been invited to provide information on the chemical substances contained in the product and to inform the waste disposal companies. 2010; International Conference on PV Module Recycling; 2010, taic Specialists Conference (PVSC), 2012 38th IEEE; 2012. validation of crystalline silicon solar cells recycling by thermal and chemical methods. It can be seen that there are opportunities and challenges related to PV recycling processes. Different EoL management strategies are being explored in the industrial and academic fields, such as recycling, remanufacturing and reusing. Contact our London head office or media team here. This step of the process generates CdCl2 and TeCl4 that are condensed and precipitated afterwards [43]. Solar Energy Materials and Solar Cells. There is potential to develop new pathways for PV waste management industry development and offer employment and prospects for both public and private sector investors. The remaining glass is exposed to a mixture of sulfuric acid and hydrogen peroxide aiming, to reach an optimal solid–liquid ratio. With this amount it is possible to produce 60 million PV modules (18 GW), which would be approximately 33% of the 2015 production [7]. development of the existing processes. Circular use of high‐purity silicon and intact silicon wafers from EoL PV modules can be economically feasible in reducing 20% of the manufacturing cost of the second‐life modules, even with some efficiency reductions. To reinforce the recycling option, currently only Europe has mandated a strong regulatory guideline, however, other nations are preparing to set up particular system for solar panel waste management. Moskowitz March 1994 Biomedical and Environmental Assessment Group Analytical Sciences Division Department of Applied Science Brookhaven National Laboratory Upton, New York 1 1973 This research was performed under the … The extraction of secondary raw material from EoL PV modules, if made in an efficient way, can make them available to the market again [68]. The process is based on a sequence of physical (mechanical and thermal) treatments followed by acid leaching and electrolysis. The company is developing a process of, from damaged solar modules.

Feed-in tariff for solar photovoltaic: The rise of Japan. Additionally, before the recycled silicon from solar cells can be used again, further chemical treatment is necessary, as well as for silver and aluminum. ... 6 This PV circular economy model has been widely explored by academic researchers, and several review papers have been published. PV Cycle was the first to, of solid recycled) [25], which is a percentage that surpasses the current European WEEE, standards. Photovoltaic recycling technologies studied worldwide. The article provides transparent and disaggregated information on the end-of-life stage of silicon PV panel, which could be useful for other LCA practitioners for future assessment of PV technologies. End-of-life (EoL) management of waste PV modules requires alternative strategies than landfill, and recycling is a valid option. A Review of Recycling Processes for Photovoltaic Modules @inproceedings{Lunardi2018ARO, title={A Review of Recycling Processes for Photovoltaic Modules}, author={M. Lunardi and J. P. Alvarez-Gaitan and J. Bilbao and R. Corkish}, year={2018} } The cumulative worldwide PV generation capacity reached 302 GW in the end of 2016 [2] and the predominant technology (90% of the market) is crystalline silicon (c-Si) cells [3]. Current projections expect the a-Si module market to disappear in the near future, since they cannot compete on costs or efficiency [3]. closed-loop use of metals. by physical operations. 2015; of recycling strategies for photovoltaic modules based on life cycle assessment. Their cell recycling system is able to extract efficient components (but not unbroken cells) from end-of-life solar modules in order to develop new green products or be reintroduced into the PV industry as new solar modules [48]. The remaining glass is exposed to a, mixture of sulfuric acid and hydrogen peroxide aiming, to reach, After that process, the glass is separated again. Japan comes next followed by India. 2007; tional Journal of Life Cycle Assessment. The environmental burden of multi-Si PV modules in China has been discussed in existing studies, however, their data are mostly from local enterprises, and none of their environmental assessment involves the decommissioning and recycling process. The summary of this process is shown in Figure 5. This step of the, system [44].

Although thin-film solar cells use far less material than c-Si cells, there are concerns, availability and toxicity of materials such, example. The “Snapshot of Global Photovoltaic Markets” aims at providing preliminary information about how the PV market developed in the last year. This study identifies the importance of encapsulating PSCs and the welding materials on the rear side of c-Si solar cells to minimize the release of toxic substances into the environment. In contrast, the data quality of CdTe PV module recycling is considered very good. FirstSolar [21] has an established recycling process for CdTe, but for other thin films there are still room for improvements. The process starts with the removal of the frames and the backsheet foil before the thermal process begins. Subsequently, these fragments are taken to a 400°C atmosphere containing chlorine gas which causes an etching process. regulatory frameworks and institutions across the globe, which is not the case at the moment. Actually, it has been shown that, for the current recycling technologies, silicon-based modules do not have enough valuable materials to be recovered and the cost of the recycling process is always higher than the landfill option (not considering the externalities), making recycling an economically unfavorable option [23]. 2014; for a recast of the WEEE directive. Hence it is vital that consumers, industry and PV producers take responsibility for the EoL of these modules. After that, for CIS only, recovered as well as the glass cullet [45]. which is not sufficient for future requirements, than the original [25]. By 2030 the top three countries for cumulative projected PV waste are projected to include China, Germany and Japan. As a result of the increase in the global market for PV energy, the end of their life will grow at the same rate in the near future. The toxicity characteristic leaching procedure (TCLP) was used to analyze the leachates from PSCs to determine the concentrations of major component species. Several studies have identified valuable components such as FTO, gold and high temperature processes as the most significant contributors to the environmental impact of PSCs. There are advantages and disadvantages of the different methods, considering. OSTI.GOV Technical Report: A review of incentives, strategies and model technologies for recycling photovoltaic modules After that, for CIS only, the EVA resin is burned and the CIS layer is grated. Lastly for recycling processes aiming to generate new materials, the aim is to keep the materials intact for reuse or direct recycling, recovering the frame, glass, tabbing and solar cells without breakages and in good condition. The new technology, appeared to solve a clear problem, the firm attachment of the glass and the cells to the EV, and the consequent difficulty to separate them simply by smashing them to pieces and sorting, NPC incorporated is one of the companies that make solar, about 40 seconds. Summary of NEDO recycling process for Si modules (pilot project). Science. Thin film processes are under development or near implementation in, materials is not sufficient when compared to production costs [26]. Nevertheless, several methods for recycling PV modules are under development. A Review of Recycling Processes for Photovoltaic Modules The installations of photovoltaic (PV) solar modules are growing extremely fast. CdTe is the most widely used thin-film technology, significant amounts of cadmium (Cd), an element, environmental problem that has been studied worldwide [37, 38]. Making of the solar cells and module fabrication holds for a greater contribution into the environment effect than in the processing of the silicon from the nature to further use in industry.

The ecodesign methodology couples the life cycle assessment method with a PVGCS design model, which is then embedded in an external optimization loop based on a multi-objective genetic algorithm, i.e., a NSGA-II variant. Nevertheless, the need, to recycle this type of waste is imminent. In USA, some states go beyond the Resource Conservation and Recovery Act which regulates hazardous and non-hazardous waste management [13]. So far, recycling processes of c-Si modules results in a net cost activity when compared to, landfill (due to the avoidance of the true environmental costs and externalities for the latter), but these processes can ensure the sustainability of the supply chain in the long-term, increase. Today, process, which starts by pyrolising the modules. Considering Si, up to 30,000 t of silicon can theoretically be recovered in 2030 [7], which is the amount of silicon needed to produce approximately 45 million new modules. It is concluded that treatment (abatement) is the only viable short-term option. Recycling photovoltaic modules. If a recycling process for PV waste that is revenue positive (i.e. The EU directive [8] established recycling targets in terms of module weight and also expresses the intention to increase the collection rates to allow the progressive recycling of more material and less to be landfilled. Solar Energy Materials and Solar Cells. All rights reserved. Once the materials/layers of a solar module can be separated, metals such as lead, copper, gallium, cadmium, aluminum and silicon can be recovered and reused in new products. The process starts with the removal of the frames, and the backsheet foil before the thermal process begins. Loser Chemie has some collection points from where they gather several types of photovoltaic systems (c-Si, CdTe, CIGS and GaAs). The PV waste manage-, ment has the potential to develop new pathways for industry development and. It is expected that by 2050 that figure will increase to 5.5, worldwide to reduce the environmental impact of PV waste and to recover some of the, value from old modules. Built by scientists, for scientists. The non-inclusion of PV residues in waste legislation in some countries is due to different reasons. Considering these findings, we have developed a rapid dismantling process allowing the recovery of all major components, saving raw materials, energy and production time in the fabrication of recycled PSCs. By Marina Monteiro Lunardi, Juan Pablo Alvarez-Gaitan, José I. Bilbao and Richard Corkish. Progress in Photovoltaics: Research and Applications. While current research into solar panels has focused on how to improve the efficiency of the production capacity, the dismantling and recycling of end-of-life (EOL) panels are seldom considered, as can be seen, for instance, in the lack of, Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. The chemicals necessary for their fabrication can be released into the environment during their disposal or following damage, such as that from natural disasters. It contains significant amounts of cadmium (Cd), an element with relative toxicity, which presents an environmental problem that has been studied worldwide [37, 38]. So far, recycling processes of c-Si modules results in a net cost activity when compared to landfill (due to the avoidance of the true environmental costs and externalities for the latter) but these processes can ensure the sustainability of the supply chain in the long-term, increase the recovery of energy and embedded materials, while reducing CO2 emissions and energy payback time (EPBT) for the whole PV industry. An overview of possible thin-film recycling processes is show in Table 2. Besides, this review believes the basics of PV panel installation, management and recycling process which could recommend upcoming guidance for the public policymakers. n biosolids processing, odour emissions, energy and carbon flows and community engagement. economic feasibility, recovery of more materials, and recovery of unbroken cells), still remain in process efficiency, complexity, energy requirements and use of non-environmentally friendly materials for the treatment of some elements.
