铅卤化物过氧化物太阳能电池的高开路电压-实验、理论和未决问题

High Open-Circuit Voltages in Lead-Halide Perovskite Solar Cells - Experiment, Theory and Open Questions

Thomas Kirchartz

摘要:

卤化铅钙钛矿的最显著的特征之一是它们具有缓慢复合的能力,尽管这些材料大多在室温下从溶液中加工。当在太阳能电池中使用铅卤化物钙钛矿层时,缓慢的复合允许实现高的开路电压。该观点讨论了我们对铅卤钙钛矿中复合和开路电压的理解和实验数据的最新水平。一个特别的重点放在开放的问题,社区必须解决设计未来的光伏和光电子器件的基础上铅卤化物钙钛矿和其他半导体具有类似的性能。

英文摘要:

One of the most significant features of lead-halide perovskites are their ability to have comparably slow recombination despite the fact that these materials are mostly processed from solution at room temperature. The slow recombination allows achieving high open-circuit voltages when the lead-halide perovskite layers are used in solar cells. This perspective discusses the state of the art of our understanding and of experimental data with regard to recombination and open-circuit voltages in lead-halide perovskites. A special focus is put onto open questions that the community has to tackle to design future photovoltaic and optoelectronic devices based on lead-halide perovskites and other semiconductors with similar properties.
