Stability Strategies and Applications of Iodide Perovskites

Iodide perovskites have demonstrated their unprecedented high efficiency and commercialization potential, and their superior optoelectronic properties, such as high absorption coefficient, high carrier mobility, and narrow direct bandgap, have attracted much attention, especially in solar cells, photodetectors, and light-emitting diodes (LEDs). However, whether it is organic iodide perovskite, organic-inorganic hybrid iodide perovskite or all-inorganic iodide perovskite the stability of these iodide perovskites is still poor and the contamination is high. In recent years, scholars have studied more iodide perovskites to improve their stability as well as optoelectronic properties from various angles. This paper systematically reviews the strategies (component engineering, additive engineering, dimensionality reduction engineering, and phase mixing engineering) used to improve the stability of iodide perovskites and their applications in recent years. This paper reviews some of the recent research advances on iodide perovskites. The stabilization strategies and applications of iodide perovskites are described separately. Among them, four aspects can be used to stabilize iodide perovskites, which are component engineering, additive engineering, dimensionality reduction engineering, and phase mixing engineering. Applications of iodide perovskites are solar cells (PSCs), light-emitting diodes (LEDs), photodetectors, etc. image
