Suppression of Undesired Losses in Organometal Halide Perovskite‐Based Photoanodes for Efficient Photoelectrochemical Water Splitting (Adv. Energy Mater. 31/2023)

Photoelectrodes In article number 2300951, Jangwon Seo, Sanghan Lee, and co-workers report efficient organometal halide perovskite-based photoanodes for photoelectrochemical water splitting. The simultaneous suppression of undesired internal external losses photogenerated carriers in is achieved by glycidyltrimethylammonium chloride treatment chemical conversion integrated catalysts, respectively, resulting a remarkable applied bias photon-to-current efficiency 12.79%. This approach provides promising strategy rational design photoelectrodes.
