Abstract

The formamidinium lead iodide (FAPbI3) perovskite has emerged as a promising material for high-efficiency photovoltaic applications. Although a power conversion efficiency of more than 26% has been achieved, stability issues have hindered its commercial application. In this study, the stability of FAPbI3 under adverse conditions such as humidity, oxygen, ultraviolet light, and temperature fluctuations is systematically reviewed. The known effective strategies for improving stability are discussed. Current studies have shown that technologies such as doping, halide alloying, additive manufacturing engineering, and interface modification have been identified as effective in mitigating phase transitions of FAPbI3 and enhancing environmental durability. Encapsulation technology further improves moisture and heat resistance. Compared with other stabilization strategies, doping and alloying can address the adverse effects of narrowing of the absorption edge. Interface engineering has an essential understanding of the stability mechanism, which will greatly improve the stability problem in the practical application of FAPbI3. This paper also looks forward to the future research directions and development trends.

期刊介绍: The journal Crystal Research and Technology is a pure online Journal (since 2012). Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of -crystal growth techniques and phenomena (including bulk growth, thin films) -modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals) -industrial crystallisation -application of crystals in materials science, electronics, data storage, and optics -experimental, simulation and theoretical studies of the structural properties of crystals -crystallographic computing
