Abstract The formamidinium lead iodide (FAPbI 3 ) perovskite has emerged as a promising material for high‐efficiency photovoltaic applications. Although power conversion efficiency of more than 26% been achieved, stability issues have hindered its commercial application. In this study, the FAPbI under adverse conditions such humidity, oxygen, ultraviolet light, and temperature fluctuations is systematically reviewed. known effective strategies improving are discussed. Current studies shown that technologies doping, halide alloying, additive manufacturing engineering, interface modification identified in mitigating phase transitions enhancing environmental durability. Encapsulation technology further improves moisture heat resistance. Compared with other stabilization strategies, doping alloying can address effects narrowing absorption edge. Interface engineering an essential understanding mechanism, which will greatly improve problem practical application . This paper also looks forward to future research directions development trends.

A site-ordered quadruple perovskites, AA′3B4O12, can have 3d transition metals at A′ and B sites, show complex magnetic interactions behavior. Additional complexity appears when arrangements are realized in AA′3B2B′2O12. In this work, RMn3Ni2Mn2O12 with R = Bi, Ce, Ho, were prepared by a high-pressure, high-temperature method about 6 GPa 1500 K. The Bi Ce samples found to crystallize space group Im-3 disordered distribution of Ni2+ Mn4+ cations one site. On the other hand, Ho sample crystallized Pn-3 showed partial ordering between two sites. structural data (and bond valence sums) suggest that cerium has oxidation state +3, which is unusual for such perovskites. Magnetic properties investigated susceptibility specific heat measurements, presence near 36 K Bi; there was evidence transitions 27 33 10 Ho. Curie–Weiss parameters estimated all from measurements up 750 total effective moment also suggests Ce3+. field 90 kOe had largest effect on sample, almost no effects sample.
