We report here all inorganic CsPbI planar junction perovskite solar cells fabricated by thermal coevaporation of CsI and PbI precursors. The best devices delivered power conversion efficiency (PCE) of 9.3 to 10.5%, thus coming close to the reference MAPbI-based devices (PCE ≈ 12%). These results emphasize that all inorganic lead halide perovskites can successfully compete in terms of photovoltaic performance with the most widely used hybrid materials such as MAPbI.
我们在此报告通过热共蒸发 CsI 和 PbI 前驱体制备的所有无机 CsPbI 平面结钙钛矿太阳能电池。最佳器件的功率转换效率（PCE）为 9.3%至 10.5%，因此接近基于 MAPbI 的参考器件（PCE ≈ 12%）。这些结果强调，所有无机卤化铅钙钛矿在光伏性能方面能够成功地与最广泛使用的混合材料（如 MAPbI）竞争。
