Abstract

A detailed analysis of the photophysical and photoelectrochemical properties of CsPbBr3 films electrochemically grown through a novel technique on fluorine-doped tin oxide is presented. An analysis of the low-temperature photoluminescence spectra reveals a strong interaction between electrons and longitudinal optical phonons. (Photo)electrochemical analysis proves that CsPbBr3 shows a p-type and recombinative behavior close to that of state-of-the-art methods to prepare CsPbBr3.
