Although solar energy is a green energy, it can produce a significant amount of waste. Some types of solar cells use rare elements or precious metals as the component material. Therefore, the recycling of PV modules is necessary for environmental and economic purposes. The recycling process for PV modules includes chemical and physical treatment methods, which have been successfully used in other recycling industries, such as electronics or hardware recycling. The use of these mature technologies can decompose and recycle PV module materials. There are still some differences between PV module recycling and electronic recycling. A solar cell module contains several encapsulating plastic materials, such as ethylene vinyl acetate (EVA) and polyvinyl fluoride (PVF). In recycling programs, removing the plastic materials is the first step. In this chapter, several types of recycling processes are introduced, which correspond to different types of PV modules. These methods have been validated and successfully implemented in PV module recycling plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
