In this study on perovskite solar cells (PVSCs), we incorporate N-benzylhydroxylamine (N-BzHoA) as an additive into the precursor solution. The addition of N-BzHoA suppressed the formation of unwanted PbI₂ and δ-phase perovskite without affecting the band gap, confirming uniform and large grains in the perovskite film. The fabricated inverted PVSCs exhibited remarkably improved properties compared to the control device, with a power conversion efficiency of 17.49%, reduced hysteresis, and more than 89% retention of the initial capacity after 100 h of light exposure. Thus, this study highlights the effectiveness of N-BzHoA as an effective additive for inverted PVSCs.

添加N-苄基羟胺改善钙钛矿薄膜质量和太阳能电池性能

在这项关于钙钛矿太阳能电池（PVSC）的研究中，我们将 N-苄基羟胺（N-BzHoA）作为添加剂加入到前驱体溶液中。 N-BzHoA的添加抑制了不需要的PbI ₂和δ相钙钛矿的形成，而不影响带隙，证实了钙钛矿薄膜中均匀且大的晶粒。与对照器件相比，所制备的倒置PVSC表现出显着改善的性能，功率转换效率为17.49%，滞后现象减少，并且在光照100小时后初始容量保留率超过89%。因此，这项研究强调了 N-BzHoA 作为倒置 PVSC 的有效添加剂的有效性。
