In other words, from an environmental point of view, insufficient toxicity and risk information exists for solar cells.
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.
Solar panels are not toxic during their use. However, improper disposal or recycling of solar panels containing lead can result in the release of lead into the environment, causing potential toxicity during their end-of-life stage. It’s important to note that the risks associated with these toxic materials are primarily related to the end-of-life stage of solar panels.
