摘要

采用两步浸泡法制备了不含有PbI₂的CH₃NH₃PbI₃钙钛矿型光吸收材料。通过真空热蒸镀制备了钙钛矿太阳能电池银背电极并观察分析了热蒸发条件对银电极的影响,进而探讨了银电极对钙钛矿太阳能电池光电性能的影响。研究发现快速沉积银电极会影响其与空穴传输层的接触,增加串联电阻,减小电荷抽取面积。另外通过暗电流曲线与光照条件下的J-V曲线对比发现,热蒸镀银电极时较强的辐射对钙钛矿电池的有机层造成了损害。

Abstract

The perovskite solar cells without PbI₂ in CH₃NH₃PbI₃ film were fabricated by two-step method,and the silver electrodes were deposited by the vacuum thermal evaporation technique.The effect of deposition parameters on silver electrode was analyzed.Furthermore,the influence of silver electrode on the photovoltaic performance of perovskite solar cells was discussed.It was found that the contact between silver electrode and HTM film would be affected by deposition rate of silver electrode,which would change the series resistance and area of charge extraction.Meanwhile,it was obtained that strong radiation during preparation of silver electrode caused damage to organic layers of perovskite solar cells by comparing the J-V curves and dark current.
