Abstract

Abstract: We have successfully demonstrated solar water splitting using a newly fabricated photoelectrochemical system with a Pt‐loaded SiC photocathode, a CoO x ‐loaded BiVO4 photoanode, and a perovskite solar cell. Detection of the evolved H2 and O2 with a 100 % Faradaic efficiency indicates that the observed photocurrent was used for water splitting. The solar‐to‐hydrogen (STH) efficiency was 0.55 % under no additional bias conditions. Abstract : Don′t take my sunshine away : Solar water splitting was successfully demonstrated in a wide range of sunlight using Pt‐loaded SiC photocathode upon combining it with a CoO x ‐loaded BiVO4 photoanode, and a perovskite solar cell. The solar‐to‐hydrogen (STH) efficiency reached 0.55 % under no‐additional bias conditions.
