我们报告了全固态锡/铅卤化物基钙钛矿太阳能电池的光伏性能。该电池具有以下组成：F掺杂的SnO 2层状玻璃/致密二氧化钛层/多孔二氧化钛层/CH 3 NH 3SnxPb（1-x）I 3/区域规则的聚（3-己基噻吩-2，5-二基）。锡卤化物钙钛矿本身不显示光伏特性。当PbI 2被添加到SnI 2中时，观察到光伏特性。CH3NH3Sn0.5Pb0.5I3钙钛矿的性能最好。在开路电压为0.42 V、填充因子为0.50、短路电流为20.04 mA/cm（2）的条件下，效率为4.18%。入射光子-电流效率曲线的边缘达到1060 nm，比CH 3 NH3 PbI 3钙钛矿太阳能电池的边缘红移了260 nm。
We report photovoltaic performances of all-solid state Sn/Pb halide-based perovskite solar cells. The cell has the following composition: F-doped SnO2 layered glass/compact titania layer/porous titania layer/CH3NH3SnxPb(1-x)I3/regioregular poly(3-hexylthiophene-2,5-diyl). Sn halide perovskite itself did not show photovoltaic properties. Photovoltaic properties were observed when PbI2 was added in SnI2. The best performance was obtained by using CH3NH3Sn0.5Pb0.5I3 perovskite. 4.18% efficiency with open circuit voltage 0.42 V, fill factor 0.50, and short circuit current 20.04 mA/cm(2) are reported. The edge of the incident photon to current efficiency curve reached 1060 nm, which was 260 nm red-shifted compared with that of CH3NH3PbI3 perovskite solar cells.
