摘要
为克服钙钛矿太阳能电池滞后效应,本文通过热注射法制得CuInS_2纳米粒子,将其以0.01%(摩尔比例)掺入甲胺/甲脒(FAPbI_3)_x(MAPbCl_3)_(1-x)混合钙钛矿中制备吸光层,并组装正向平面异质结钙钛矿太阳能电池,掺杂CuInS_2器件的正向扫描光电转化效率达15.66%,反向扫描结果达15.36%,两者仅相差1.95%;而未经掺杂的器件正向扫描光电转化效率为15.14%,反向扫描结果为13.58%,两者相差11.49%。结果表明,在(FAPbI_3)_x(MAPbCl_3)_(1-x)混合钙钛矿吸光层中掺杂CuInS_2有利于相应器件磁滞效应等各项性能的提升。
In order to overcome the hysteresis effect of perovskite solar cells,CuInS_2 nanoparticles by hot injection method were doped into (FAPbI_3)_x(MAPbCl_3)_(1-x) perovskite film with the molar ratio of 0.01%.The forward-scanning(FS) PCE of the perovskite device doped by CuInS_2 was up to 15.66% with the reverse-scanning(RS) result of 15.36%,and the difference of PCE between FS and RS was only 1.95%.However,the forward-scanning PCE of the undoped device was 15.14%,with the reverse-scanning result of13.58%,and the difference of PCE was 11.49%.The experimental results show that the addition of CuInS_2 in the(FAPbI_3)_x(MAPbCl_3)_(1-x) mixed perovskite absorber can improve the performance of the corresponding devices,including considerably reducing the hysteresis effect of the device.
