MOFs based on the application and challenges of perovskite solar cells

In recent years, perovskite solar cells (PSCs) have attracted much attention because of their high energy conversion efficiency, low cost, and simple preparation process. Up to now, the photoelectric efficiency has been increased from 3.8% 25.5%. Metal–organic skeleton-derived metal oxides composites (MOFs) are widely considered for application in PSCs due flat charge/discharge potential plateau, capacity, stable cycling performance. By combining MOFs PSCs, based on composition materials film, electron transport layer, hole interfacial interlayer this article discusses photovoltaic performance or structure optimization effect each function which is great significance improve cell. The problems faced by summarized, next research directions discussed, development crossover area MOFs–PSC foreseen accelerate comprehensive popularization PSCs. So far, devices with higher all organic–inorganic hybrid perovskites, relatively hot better properties contain organic ions. External factors, such as humidity, temperature, pressure, light, electric field, chemical environment, strongly influence characteristics functions absorber layer. degradation device directly related its structural material instability. general, main factors affecting stability can be summarized intrinsic material, ion migration device, component stability. mainly includes wet stability, thermal phase When exposed a humid water molecules first diffuse into membrane form hydrogen bonds volatile components, forming reversible monohydrate phase. increase content subsequently leads irreversible permanent loss dihydrate molecules, eventually degrades PbX2 substances (CH3NH2, HI, NH3, I2, CH3I) (Zhu et al., 2016Zhu Z.
