A Perovskite Photovoltaic Mini-Module-CsPbBr₃ Photoelectrochemical Cell Tandem Device for Solar-Driven Degradation of Organic Compounds.

ABSTRACT: Recently, halide perovskites have been widely explored for high-efficiency photocatalysis or photoelectrochemical (PEC) cells. Here, in order to make an efficient photoanode electrode for the degradation of pollutants, concretely 2-mercaptobenzothiazole (MBT), nanoscale cesium lead bromide (CsPbBr₃) perovskite was directly formed on the surface of mesoporous titanium dioxide (meso-TiO₂) film using a two-step spin-coating process. This photoelectrode recorded a photocurrent of up to 3.02 ± 0.03 mA/cm² under standard AM 1.5G (100 mW/cm²) illumination through an optimization process such as introducing a thin aluminum oxide (Al₂O₃) coating layer. Furthermore, to supply high voltage for efficient oxidation of MBT without an exte
