Ag/CuO nanofibers (Nfs) with a diameter of 650 nm were successfully prepared via electrospinning Ag doped CuO nanofibers and then calcined at 450°C for 2 hours. By using Ag/CuO Nfs and PEDOT:PSS as the hole transport layer, an optimum perovskite solar cell power conversion efficiency (PCE) of 11.6% was achieved, which was 33% higher than that of the original perovskite solar cells (8.7%). The devices showed a high PCE because of the high cavity mobility of the Ag/CuO Nfs/PEDOT:PSS films. At the same time, the Ag/CuO Nfs could also slow down the hydrolysis and corrosion of the perovskite by acidic PEDOT:PSS, and increase the environmental stability of the solar cells.

通过将Ag掺杂到CuO纳米纤维中作为空穴缓冲层来制备高效钙钛矿太阳能电池

通过电纺制掺Ag的CuO纳米纤维，成功制备了直径650 nm的Ag / CuO纳米纤维（Nfs），然后在450°C下煅烧2小时。通过使用Ag / CuO Nfs和PEDOT：PSS作为空穴传输层，最佳钙钛矿太阳能电池功率转换效率（PCE）为11.6％，比原始钙钛矿太阳能电池（8.7％）高33％。 。由于Ag / CuO Nfs / PEDOT：PSS薄膜具有很高的腔迁移率，因此该器件具有较高的PCE。同时，Ag / CuO Nfs还可以减缓钙钛矿被酸性PEDOT：PSS的水解和腐蚀，并增加太阳能电池的环境稳定性。
