Abstract

This chapter discusses the potential hazards associated with solar cells. There are environmental, health, and safety hazards associated with the manufacturing of solar cells. The photovoltaic (PV) industry uses toxic and flammable substances, although in smaller amounts than many other industries, and use of hazardous chemicals can involve occupational and environmental hazards. In manufacturing photovoltaic cells, health may be adversely affected by different classes of chemical and physical hazards. Chemical hazards with solar cells are related to the materials' toxicity, corrosivity, flammability, and explosiveness. These hazards differ for different thin-film technologies and deposition processes. This chapter discusses main hazards associated with specific technologies and lists hazardous materials used in manufacturing. The chapter also explains public health and environmental issues associated with solar cells. Occupational safety issues related to Cadmium Telluride (CdTe) solar Cells, Copper Indium Diselenide (CIS) solar Cells, and Gallium Arsenide (GaAs) high efficiency solar cells are explained. Operation of PV modules and photovoltaic module decommissioning is also described in the chapter.
