The effects of organic cation rotation in hybrid Organic-Inorganic Perovskites: A critical review

Abstract

The emergence of hybrid organic–inorganic perovskites (HOIPs) has made great progress in the photovoltaic (PV) field. In recent years, more and more articles have shown that the modification of organic cations can improve HOIPs’ performance, and a surge of interest has been paid to rethink the effect of organic cations. In our review, we summarized the influences of organic cation rotation on structure, optoelectrical properties, and stability. We also provide theoretical insights into why and how organic cations affect the performance of HOIPs in experiments. At last, we have proposed possible control methods and development directions in the hope that the rotation of organic cation can be better observed and utilized in inherently tunable perovskite materials, solar cells, LED, photocatalysis, photothermal conversion, and other related fields.
