Photoelectrochemical (PEC) devices that use semiconductors to absorb solar light for water splitting offer a promising way toward the future scalable production of renewable hydrogen fuels. However, charge recombination in photoanode/electrolyte (solid/liquid) junction is major energy loss and hampers PEC performance from being efficient. Here, we show this problem addressed by conformal deposition an ultrathin p-type NiO layer on photoanode create buried p/n as well reduce at surface...
Appropriate nanostructuring and morphology control significantly improves front illumination performance optical properties of a transparent BiVO4 photoanode, with record high charge separation efficiency at 0.6 V versus the reversible hydrogen electrode.

An electrodeposited Cu2ZnSnS4 (CZTS) compact thin film modified with an In2S3/CdS double layer and Pt deposits (Pt/In2S3/CdS/CZTS) was used as a photocathode for water splitting of hydrogen production under simulated sunlight (AM 1.5G) radiation. Compared to platinized electrodes based on bare CZTS (Pt/CZTS) CdS single (Pt/CdS/CZTS), the Pt/In2S3/CdS/CZTS electrode exhibited significantly high cathodic photocurrent. Moreover, coverage In2S3 found be effective stabilization against...
