Solar energy is considered clean energy, and its use is predicted to increase in the near future. Most installed units today are crystalline solar cells, but the field is in constant development, and when the first dye sensitized solar cell was published by Grätzel and O''Reagan a new, third-generation, solar power was born. Highly toxic metals are used to produce the photovoltaic

Reported in Solar Energy Materials and Solar Cells, the study draws attention to perovskite components other than lead, suggesting that metal''s toxicity, by comparison, could be overestimated.
Perovskite solar cells (PSCs) as an emerging renewable energy technology are expected to play an important role in the transition to a sustainable future. However, lead toxicity of PSCs remains a
Despite such promising prospects, the market breakthrough of PSCs is impeded by two major challenges: poor long-term stability and potential lead toxicity. 32–34 Stability has been a long-lasting problem for PSCs, which primarily arises from the decomposition of the perovskite film into its precursors. 35,36 In addition, perovskite films are also degraded by
In other words, from an environmental point of view, insufficient toxicity and risk information exists for solar cells.

For silicon solar cells, PERC and module fabrication accounted for up to 70 % of the total life cycle freshwater toxicity impacts ( Lunardi et al., 2019 ), and silicon wafers contributed to about 60 %–70 % of the total life cycle freshwater toxicity impact, mainly due to the monocrystalline silicon ingot manufacturing ( Jia et al., 2021 ).
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.
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.
