A solution processed Sb2S3-based photocathode with enhanced photocatalytic performance via constructing an ultrathin TiO2 overlayer and noble metal modification

An ultrathin TiO₂ overlayer was deposited on nano-structured Sb₂S₃ absorption layers by a simple electrodeposition method, effectively increasing photoelectrochemical conversion and the onset potential of a photocathode for solar water splitting.
