Scientists from Skoltech and other research centers have systematically studied the toxicity of materials used in perovskite solar cells. They conclude that, once the remaining technological hurdles are overcome, mass production of this potentially cheap and efficient alternative to silicon-based photovoltaics should not cause any significant environmental risks and health hazards. 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.
