Cu2O Photocathodes with Bidirectional CuSCN Layers to Improve Charge Separation for Enhanced Photoelectrochemical Water Splitting

“…Therefore, hole-trapping materials are essential to efficiently separate charges. CuSCN with high hole mobility (0.01–0.1 cm 2 V –1 s –1 ), wide band gap (3.6–3.9 eV), and high electrical conductivity and chemical stability has significant advantage in enhancing the performance of solar cells. , Among methods for CuSCN, the electrochemical deposition method is suitable for various shapes of substrates and can achieve uniform deposition and is often used to prepare nanostructured CuSCN. − Recent studies have preliminarily confirmed that CuSCN has the feasibility to be used as a photocathode back contact. − Therefore, how to construct more efficient charge-separated nanostructures based on the design of a CuSCN structure to suppress the recombination effect of photogenerated carriers is still an open question.…”
