Using time-resolved in situ X-ray photoelectron spectroscopy, we identify and suppress rapid degradation mechanisms for cesium-stabilized formamidinium lead iodide perovskite materials used in state-of-the-art photovoltaics. The order of po toxicity of the hydroxides was potassium > rubidium > cesium; cesium iodide was more toxic than rubidium iodide. Cesium is a naturally-occurring element found in rocks, soil and dust at low concentrations. COVID-19 is an emerging, rapidly evolving situation. Lead halide perovskites are emerging as important candidates for many photoelectric applications; however, the toxicity of the heavy metal Pb poses a barrier to such applications. These results indicate that cesium is only slightly toxic acutely and would pose an acute health hazard only when ingested in large quantities. Here, we report on the synthesis and transformation of the cesium copper halides Cs 3 Cu 2 I 5 and CsCu 2 I 3. These studies indicate that cesium and rubidium are only slightly toxic on an acute toxicologic basis and would pose an acute health hazard only when ingested in large quantities. The efficiency is high and energy dispersive spectroscopy is possible, but the resolution is rather poor. Chronic iodide overdoses may result in iodism, which is commonly characterized by salivation, coryza, sneezing, conjunctivitis, headache, fever, laryngitis, bronchitis, stomatitis, parotitis and oedema of the glottis [L2061]. Lithium fluoride Sodium fluoride Potassium fluoride Rubidium fluoride Francium fluoride: Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Cesium iodide did not affect the eye or skin. COVID-19 is an emerging, rapidly evolving situation.
