Insufficient toxicity and environmental risk information currently exists. However, it is known that lead (PbI 2), tin (SnI 2), cadmium, silicon, and copper, which are major ingredients in solar cells, are harmful to the ecosystem and human health if discharged from broken products in landfills or after environmental disasters.
Toxicity of perovskite, silicon, CdTe, and CIGS based solar cells were investigated. Potential leaching compounds from solar cells were reviewed. The environmental impacts of leaching compounds/ingredients should be determined. Photovoltaic (PV) technology such as solar cells and devices convert solar energy directly into electricity.
Current and emerging photovoltaic modules may include small amounts of toxics. Global toxicity characterization policies for photovoltaic devices are compared. Sampling approach, particle size, and methods cause leachate result variability. Limitations of current assessment procedures and regulations are disclosed.
Risks of contamination by leachates containing harmful chemicals are linked to environmental disasters (hurricanes, hail, and landslides). However, research into the health and environmental safety of solar cells is rare, despite the fact that solar cell devices contain harmful chemicals such as Cd, Pb, Sn, Cu, and Al.
The toxicity of CdTe PV solar cells (Morgan et al., 1997; Zayed and Philippe, 2009; Tammaro et al., 2016) has been reported for rats, bacteria, water fleas, and green algae. Two toxicity studies on rats used CdTe reagents and one ecotoxicity study used leachates after fragmentation and pure water treatment.
