Recycling technologies for this type of panels have been widely increasing in recent years. However, the end-of-life phase has been generally excluded or neglected from these analyses, mainly because of the low amount of panels that reached the disposal yet and the lack of data about their end of life. The results show that recovery of materials from solar modules results in lower environmental impacts compared to other EoL scenarios, considering our assumptions. 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. to the needs and circumstances of each region or country. These conditions result in the delamination of the EVA. Journal of Materials Science: Materials in Electronics. 20th European Photovoltaic Solar Energy Conference, Barcelona, Spain; 2005. which is not sufficient for future requirements, than the original [25]. The realities show that the current pace of climate change exceeds historical changes. The processes are well developed for mono or multicrystalline silicon. All rights reserved. of 2016, cumulative global PV waste streams are expected to have reached 43,500-250,000 metric DOI: 10.5772/intechopen.74390 The problem of utilization and recycling become a cornerstone, since these processes can also affect the environment and accelerate For c-Si, the recycling strategy significantly reduces the EPBT (a factor of 1.8 is observed from the 100% virgin to the 100% recycled scenario) when considering an identical PV module efficiency and a significant decrease in Global Warming Potential (GWP), expressed in g CO2 eq per kWh, is also observed with a 20% reduction in the more extreme case. It accounts for about half of the energy, carbon footprint, and cost to produce PV modules, but only a small portion of their mass. Predictive maintenance is a field of research that has emerged from the need to improve the systems in place. people during their lives produce many waste, as the consumption is an integral part of any person. Besides that, Si-based tandem solar technologies are expected to appear in mass production after 2019 [7]. These efforts are part of an industry-led voluntary product management arrangement to address the potential emerging risks of PV systems and their waste. This is made by setting aside funds by the company itself at the time of the module sale, which also happens with WEEE. material and the emergence of new solar PV end-of-life industries. Ministers agreed that the state of Victoria would lead innovative programs that seek to reduce the environmental impacts caused throughout the lifecycle of photovoltaic systems. Waste and, silicon photovoltaic modules. With this amount it is possible to produce 60 million PV modules (18 GW), which would be approximately 33% of the 2015 production [7]. Also, for recycling CdTe modules, ANTEC Solar GmbH designed a pilot plant with a similar technology to the First Solar process. Additionally, before the recycled silicon from solar cells can be used again, further chemical treatment is necessary, as well as for silver and aluminum. In later sections, the environmental impacts of PV systems are discussed, considering the life cycle stages in three broad categories: manufacturing, operational, and end of life. The company has developed and patented original, processes using mechanical and chemical treatment to recycle solar cells [47]. Thin film processes are under development or near implementation in Italy, Japan and South Korea but costs are not yet competitive. Thin-film solar modules recycling processes. In dieser Zeit, in der vielerorts erwogen wird, wie diverse Materialien aus Rohstofflagerstätten mit geringsten Gehalten gewonnen werden können, eröffnet sich ein vielversprechender Weg – die Wiederverwendung, das Recycling. In USA, some states go beyond the Resource Conservation and Recovery Act which regulates hazardous and non-hazardous waste management [13]. The use of hazardous metals like lead, cadmium in solar photovoltaics (PVs) are rapidly increasing which poses the risk to the environment due to potential release of these constituents. PV Cycle is a not-for-profit organization which goal is to manage PV waste through their waste management programme for solar PV technologies [42]. However, the current waste volumes are still low, which entails economical obstacles for the development of the existing processes. However, this will not occur. dedicated solar-panel recycling plants. US Patent # 6,572,782; 2003, 20161117-INCOMING/Tech-Science/Japanese-companies-work-on-ways-to-recycle-a-, mountain-of-solar-panels. lines on how to properly dispose of EoL photovoltaic modules. Even up to 90% recovery of materials is not sufficient when compared to production costs [26]. Comparison of these characteristics to the fundamental limits based on the Shockley-Queisser detailed-balance model provides a basis for identifying the key limiting factors, related to efficient light management and charge carrier collection, for these materials.
