研究目的
To review the potential environmental risks of leachates derived from solar cell devices, focusing on toxicity and leaching potential, and to discuss related challenges and policy initiatives for minimizing these risks.
研究成果
The review concludes that lead (PbI2), tin (SnI2), cadmium, silicon, and copper, major ingredients in solar cells, are harmful to both ecosystem and human health if discharged from fragmented landfill products or after environmental disasters. It suggests future research directions for improving the amount of scientific evidence and enabling more sustainable and safe usage of photovoltaic technologies, including the ecotoxicity of leachates from solar cell devices and global investment in environmental risk assessments based on experimental data.
研究不足
Insufficient toxicity and environmental risk information currently exists for solar cells. The review highlights the lack of data on the ecotoxicity of leachates or its main ingredients, especially for older solar cells (crystalline silicon-based solar cells) and emerging solar cells (perovskite-based solar cells).
