摘要

背电极是影响钙钛矿太阳电池性能的一个重要因素. 本文采用COMSOL软件仿真研究了背电极材料、结构、厚度对电池性能的影响规律. 发现相对于背电极金属的功函数, 其阻值对电池性能影响小. 背电极结构除了阻值会影响电池性能, 还存在影响电池性能的其他因素. 蜂窝结构背电极中, 考虑制作难易程度的情况下, 圆形半径约等于边缘间距时性价比最高. 预测背电极中每增加10%的孔隙, 电池性能大约提升5%. 背电极阻值随着厚度的增加而减小, 考虑工艺、成本等因素的前提下, 最佳的厚度应在100—150 nm之间.

Abstract

The back electrode is an important factor affecting the performance of perovskite solar cells. In this paper, the effects of back electrode material, structure and thickness on the performance of perovskite solar cells are studied by using COMSOL software. It is found that compared with the work function of the back electrode metal, its resistance has small effect on solar cell performance. Besides the back electrode structures affecting cell performance, there are other factors affecting cell performance. In terms of the back electrodes with honeycomb structure, considering the difficulty in fabricating, the best cost performance occurs when the radius of the circle is approximately equal to the edge spacing. It is predicted that the cell performance will be improved by about 5% in porosity with increasing 10% in the back electrode. The resistance of the back electrode decreases with its thickness increasing. Considering the process and cost, the optimal thickness should be between 100 nm and 150 nm.
