Abstract

以聚酰亚胺为基底的柔性钙钛矿太阳电池因其出色的热稳定性和高功质比可应用于航天飞行器。然而，聚酰亚胺的金属电极会造成钙钛矿太阳电池非辐射复合增大，降低钙钛矿太阳电池的转换效率。因此，本文介绍了一种采用ITO修饰策略来提升柔性钙钛矿太阳电池转换效率的新方法。通过在金属电极上沉积一层ITO，不仅提高了空穴传输层中Ni3+/Ni2+的比例，提高了空穴传输层的电导率，还改善了钙钛矿薄膜成膜质量，抑制了钙钛矿薄膜与氧化镍界面之间的非辐射复合。基于ITO修饰策略制备的聚酰亚胺基底柔性钙钛矿太阳电池转换效率达17.91%。本文为提升聚酰亚胺基底的柔性钙钛矿太阳电池的转换效率提供了一种有效途径。
