A new passivator—benzoyl hydrazine (BH) with carboxyl, hydrazine and phenyl groups was developed to effectively passivate defects in CsPbI₃ through synergetic effects of these groups. Consequently, a highest efficiency of 20.47 % with a high open-circuit voltage and stability is achieved in a BH-CsPbI₃ solar cell, the highest efficiency among all pure CsPbI₃-based devices reported to date.

用于纯 CsPbI3 钙钛矿太阳能电池缺陷钝化的酰肼衍生物

开发了一种新的钝化剂——苯甲酰肼（BH），它具有羧基、肼和苯基，通过这些基团的协同作用有效地钝化了 CsPbI _{3中的缺陷。}_{因此，在 BH-CsPbI 3}太阳能电池中实现了 20.47% 的最高效率以及高开路电压和稳定性，这是迄今为止报道的所有纯 CsPbI ₃基器件中的最高效率。
