摘要
为了研究退火工艺对平面型倒置钙钛矿太阳能电池性能的影响,利用MAPbI_(x)Cl_(3-x)作为光活性层,PEDOT:PSS为空穴传输层,PC_(61)BM为电子传输层,BCP为阴极界面修饰层,系统研究了退火时间对钙钛矿薄膜的微观形貌、结晶性能、光吸收性能等的影响规律,探索了退火工艺对钙钛矿太阳能电池性能的影响。实验结果表明,退火时间为5 min时可获得高平整度、高结晶性及高吸光性的钙钛矿薄膜。基于这一钙钛矿薄膜,最终获得了最高效率达15.79%的倒置平面型钙钛矿太阳能电池器件。此外,该类型器件还具有出色的稳定性能及低回滞效应。
In order to study the effect of annealing process on the performance of planar inverted perovskite solar cells,high efficiency inverted perovskite solar cells in planar configuration are successfully fabricated.In devices,MAPbI_(x)Cl_(3-x) is used as a photoactive layer,PEDOT:PSS is used as a hole transport layer,PC_(61)BM is used as a electron transport layer and BCP is used as a electron transportlayer.The effects of annealing time on the microstructure,crystallization and optical absorption properties of perovskite films were studied systematically.The effect of annealing processes on the performance of perovskite solar cells was investigated.It is found that the optimized annealing time is 5 min for perovskite thin films with high smoothness,crystallinity and absorption.Based on the optimized perovskite films,the highest power conversion efficiency of inverted perovskite solar cells in planar configuration is improved up to 15.79%.In addition,this type of device also shows excellent stability performance and low hysteresis.
