摘要

Sn基钙钛矿材料因其无毒、较宽带隙和热稳定性成为太阳能电池研究领域的热点。本文利用SCAPS-1D软件构建了结构为FTO/TiO2/CH3NH3SnI3/Spiro-OMeTAD/Ag钙钛矿太阳能电池并对其相关性能进行了数值计算。研究了钙钛矿光吸收层厚度、空穴传输层厚度、空穴传输层和钙钛矿光吸收层间面缺陷,以及工作温度对器件性能的影响, 然后对器件性能进行优化。经优化后, 钙钛矿太阳能电池的光电转换效率为30.955%。通过理论分析进一步为提高钙钛矿太阳能电池的光电转换效率提供了新的思路。

Abstract

With non-toxic nature, wide bandgap, and thermal stability, Sn-based perovskite materials have become a hot topic in the field of perovskite solar cell research. In this paper, the SCAPS-1D software was used to construct the FTO/TiO2/CH3NH3SnI3/Spiro-OMeTAD/Ag perovskite solar cells and the performances of the constructed cells were calculated. The effects of the thickness of absorption and hole buffer layer, the surface defects between hole buffer layer and absorption layer, and the operating temperature on the device performance were studied, then the device performance was optimized. The photoelectric conversion efficiency of the optimized perovskite solar cell is 30.955%. The theoretical analysis suggests a new approach for enhancing the photoelectric conversion efficiency of perovskite solar cells.
