Abstract

Large-area polydimethylsiloxane (PDMS) films with variably sized moth-eye structures were fabricated to improve the efficiency of perovskite solar cells. An approach that incorporated photolithography, bilayer PDMS deposition and replication was used in the fabrication process. By simply attaching the moth-eye PDMS films to the transparent substrates of perovskite solar cells, the optical properties of the devices could be tuned by changing the size of the moth-eye structures. The device with 300-nm moth-eye PDMS films greatly enhanced power conversion efficiency of ~ 21% due to the antireflective effect of the moth-eye structure. Furthermore, beautiful coloration was observed on the 1000-nm moth-eye PDMS films through optical interference caused by the diffraction grating effect. Our results imply that moth-eye PDMS films can greatly enhance the efficiency of perovskite solar cells and building-integrated photovoltaics.

摘要

制备了具有不同尺寸蛾眼结构的大面积聚二甲基硅氧烷（PDMS）薄膜，以提高钙钛矿太阳能电池的效率。在制造过程中采用了一种结合光刻、双层PDMS沉积和复制的方法。通过简单地将蛾眼PDMS薄膜附着到钙钛矿太阳能电池的透明基板上，可以通过改变蛾眼结构的尺寸来调整器件的光学性能。由于蛾眼结构的抗反射作用，具有300纳米蛾眼PDMS薄膜的器件大大提高了功率转换效率，达到了约21%。此外，通过衍射光栅效应引起的光学干涉，在1000纳米蛾眼PDMS薄膜上观察到了美丽的色彩。我们的结果表明，蛾眼PDMS薄膜可以大大提高钙钛矿太阳能电池和建筑一体化光伏的效率。
