“…As a result, smaller perovskite crystallites were developed with enhanced stability, morphology, and photoelectronic characteristics. Efficiencies of >16% were obtained which good reproducibility and stability where 95% of the initial efficiency is maintained after 1000 h. 136 Snaith and coworkers reported, in 2016, the stability of cesium lead mixed-halide perovskites (CsPbI 2 Br) in its cubic phase at room temperature even when bulk material is used. 137 This material shows a bandgap range between 1.82 and 1.92 eV, which depends on the growth technique.…”

solution processes and have been proved to have similar optoelectronic properties with their organic counterparts. [24][25][26] So far, CsPbX 3 perovskites have been widely studied as alternative light absorbers in PSCs and considerable efforts are being made to improve device performance. [27][28][29][30][31][32][33][34] Among these efforts, organic molecular engineering in CsPbX 3 perovskites are the most straightforward method to improve device stability and PCE. [31,32] Since CsPbX 3 PSCs were first reported in 2015, great progress has been made on organic molecular engineering and over 19% PCE has been achieved. [35][36][37][38][39] In this review, we systematically reviewed and discussed the current development of organic molecular engineering in inorganic CsPbX 3 PSCs. First, structure evolution induced by organic molecular engineering was demonstrated. Then, the progresses on the inorganic CsPbX 3 PSCs will be reviewed and discussed in detail according to different molecule function (alloying in perovskite structures, as sacrificial agents, forming 2D structures, and modifying surfaces and interfaces). Finally, the current issues of molecular engineering will be pointed out and future directions will be highlighted.

Although the power conversion efficiency (PCE) of perovskite solar cells (PSCs) increases rapidly, there are still some issues that limit their commercialization. The perovskite is sensitive to the water molecules, increasing the difficulty in the preparation of perovskite films in ambient condition. Most high-performance PSCs based on conventional method are required to be prepared in inert atmosphere condition, which increase the fabrication cost. To fabricate the high-quality perovskite in ambient condition, we preheated the substrates and selected the proper anti-solvent. As a result, the target perovskite films show a better crystallinity compared with perovskite film prepared via the conventional one-step deposition method in ambient condition. The PSCs prepared in ambient condition yield the improved PCE of 16.89% from a PCE of 11.59%. Compared with the reference devices, the performance stability of target PSCs is much better than that of reference PSCs.
