Most perovskite solar panels contain lead, a known toxicant. In consequence there is a growing concern regarding its accidental release during operation. We evaluated the potential life cycle toxicity impacts of Pb, and four other metals found in perovskite solar panels—Ag, Cu. In, and Sn. We focused on their use in integrated applications—urban, agrivoltaic, buildings, and floating solar. Preliminary results indicated only the mining of silver is more ecotoxic than that of lead on a mass basis. During a catastrophic break, only silver emissions, and only for floating photovoltaics are more ecotoxic than those of lead. In all other cases, metals evaluated are potentially as toxic as lead.
