摘要

钙钛矿和黄铜矿材料是高效全薄膜串联太阳能电池的极好吸收剂。这项工作为这种装置提供了认证的世界纪录，在稳态条件下实现了24.6±1.1%的功率转换效率。从认证的电流-电压测量中提取的最佳IV参数显示短路电流密度约为19.3 mA/cm2，开路电压为1.765 V，填充系数为71.8%。与我们之前的记录相比，电流密度大大提高，主要是由于底部亚电池的带隙降低和顶部钙钛矿电池的光学性能改进。

Improving Perovskite/CIGS Tandem Solar Cells for Higher Power Conversion Efficiency through Light Management and Bandgap Engineering.

Perovskite and chalcopyrite materials are excellent absorbers for highly efficient, all-thin-film tandem solar cells. This work presents a certified world record for such a device, achieving a power conversion efficiency of 24.6 ± 1.1% under steady-state conditions. The best IV parameters extracted from certified current-voltage measurements presented a short-circuit current density of around 19.3 mA/cm², an open-circuit voltage of 1.765 V, and a fill factor of 71.8%. In comparison to our previous record, the current density improved considerably, mainly due to the lowering of the bandgap of the bottom subcell and the improved optics of the top perovskite cell.
