“…The PEC-WS property of TiO 2 was initially reported, so n-type metal oxides such as (Fe 2 O 3 , BiVO 4 , ZnO etc) have been widely studied as an effective candidate for water oxidation. Amidst them, ZnO acts as a conventional photoanode having substantial photocatalytic and STH conversion efficiency based on its suitable band edge position, cost-effective and innocuous property, remarkable photoelectrochemical and thermal stability (3,4).…”

Harvesting energy from the sun is contemplated to be one of the notable choices to meet the ever-increasing energy demands of the current progressive society. Photoelectrochemical splitting of water (PEC-WS) into H2 and O2 turned out to be a constructive strategy to overcome the prevailing energy crunch. In this present work, ZnO is doped with different concentrations of Sn and coupled with CuI to construct a p-n heterostructure. Compared to bare ZnO, CuI/5% Sn-ZnO manifested better absorbance in the visible region, enhanced photocurrent density (1.08 mA/cm2), more negative flat band potential, high charge carrier density and least semi-circular arc radius in Nyquist plot. Hence, the present work delineates p-n heterostructure and their nano-engineering opens a potential route for fabricating light-harvesting photoelectrodes to be used for an improved PEC-WS applications.
