Highly Efficient and Stable CsPbBr3 Perovskite Photoanodes Based on Inverse Opal TiO2 Layers in Photoelectrochemical Water Splitting. CsPbBr3, an inorganic halide perovskite compound, has attracted significant attention in the photoelectrochemical water splitting (PEC-WS) process due to its excellent properties; i.e. low cost, processing at ambient temperature and humidity, tunability of the bandgap, long carrier transport length, and reasonable stability.

Compared to traditional optoelectronic materials [[1], [2], [3], [4]], perovskite optoelectronic materials are widely used in light-emitting diodes [[5], [6], [7]], solar cells [[8], [9], [10]], photodetectors [11,12], and lasers [13,14] due to their advantages, including high color purity, tunable spectra, and simple preparation processes.

In this study, it has been tried to demonstrate the implications of employing nonsimilar mesoporous TiO2 templated films as interfacial blocking layers for improving the input light transmittance and photovoltaic performance of dye sensitized and perovskite solar cells.
