Abstract CsPbIBr2, a type of cesium based all-inorganic halide perovskite (CsPe) composition, has been proposed as an alternative perovskite material against the mainstream organic–inorganic hybrid halide perovskite (HPe) materials owing to its exceptional humidity, thermal, temperature, and light stability. However, the low power conversion efficiency (PCE) due to its wide bandgap (2.05 eV) is an obstacle for its application in developing highly efficient solar cells. In this study, facile nanoimprinted one-dimensional grating nanopattern (1D GNP) formation on mesoporous TiO2 (mp-TiO2) photoelectrode has been introduced to improve the effective light utilization for enhancing the performance of CsPbIBr2 perovskite solar cells (PSCs). The 1D GNP structure on mp-TiO2 layer can not only increase the light absorption efficiency by diffracting the unabsorbed light into the mp-TiO2 and CsPbIBr2 active layer, but can also increase the charge separation and collection due to the enlarged interfacial contact area between the mp-TiO2 and CsPbIBr2 layers. Consequently, both current density (JSC) and fill factor (FF) of the fabricated cells were improved leading to over 20% improvement in their PCE. Thus, we conclude that this periodic grating structure, fabricated by simple solvent-assisted nanoimprinting, can play an important role in the realization of high-efficiency and low-cost Cs-based PSCs.

Perovskite solar cells to date are made of polycrystalline films which contain a high density of defects. Imperfection passivation to reduce non-radiative recombination and suppress ion migration could improve device efficiency and device stability.
