Organometal halide perovskites, in particular lead (Pb)‐based ones, are the most promising light absorbers for thin‐film solar cells. Despite the power conversion efficiencies of Pb‐based perovskite solar cells (PSCs) increasing from 3% to a certified efficiency of 23%, some serious issues need to be addressed to commercialize these solar cells, mainly, the presence of Pb and its moisture sensitivity. Herein, highly stable organic–inorganic copper (II)‐based perovskites are reported as alternatives to the existing Pb perovskites by introducing a novel architecture of mesoscopic PSCs. Apart from a remarkable open circuit voltage of 370 mV with a power conversion efficiency of 0.63%, the present PSCs shows excellent water stability and optoelectronic properties for photovoltaic applications.

基于有机-无机铜（II）的钙钛矿：面向光伏应用的低毒性和耐水吸光剂的良性方法

有机金属卤化物钙钛矿，特别是铅（Pb）基钙钛矿，是薄膜太阳能电池最有前途的光吸收剂。尽管基于铅的钙钛矿太阳能电池（PSC）的功率转换效率从3％提高到23％的认证效率，但仍需要解决一些严重的问题才能使这些太阳能电池商业化，主要是铅的存在及其对湿度的敏感性。在此，通过引入介观PSC的新型结构，据报道，高度稳定的基于有机-无机铜（II）的钙钛矿可替代现有的Pb钙钛矿。除了具有370 mV的显着开路电压和0.63％的功率转换效率外，目前的PSC还显示出优异的水稳定性和用于光电应用的光电性能。
