Perovskite (photo)electrochemistry

We perform electrochemical and photoelectrochemical experiments on optically active lead halide perovskite materials. The goal is to better understand their optoelectronic properties, identify degradations mechanisms, and ultimately employ them as photoelectrodes in solar fuels generation.
