Photoelecrochemical (PEC) water splitting is most promising process which can produce green hydrogen. To achieve efficient and stable unassisted solar water splitting, development of organometal halide perovskite (OHP)-based photoelectrodes is highly desired due to the excellent optoelectronic characteristics. However, stable utilization of OHP-based photoelectrodes is significantly challenging because they are vulnerable to water molecules. In this talk, highly efficient and stable OHP-based photoelectrodes achieved by metal encapsulation method will be introduced. Furthermore, the OHP-based dual photoelectrodes for unassisted solar water splitting will be discussed. We successfully fabricated OHP-based PEC systems composed of highly efficient and stable OHP photocathodes and photoanodes. We believe that the OHP-based PEC system afford us opportunities to achieve the future practical application of OHP-based PEC systems for efficient and stable solar H2 production.
