In the race of using solar energy, perovskite solar cells have attracted interests by dint of its breakthrough improvement in power conversion efficiency to nearly 20% within several years. However, application of organic metal halide (OMH) perovskites in photoelectrolysis of water for energy storage has not been placed in proper care due to their low stability. Herein, we report a photoelectrochemical water oxidation using OMH perovskite materials as both the light absorber and energy converter. Perovskite-based photoanodes not only yielded a high photovoltage and current output but also exhibited a substantial stability for as long as hundreds of seconds, which is a very positive sign in applications of perovskites. Furthermore, we are developing new perovskite-like materials with higher stability and more suitable band gap for water splitting. This will pave the way for perovskites to find more application in the solar energy.
