Significantly enhanced photocurrent for water oxidation in monolithic Mo:BiVO/SnO/Si by thermally increasing the minority carrier diffusion length

Transition-metal-oxide semiconductors are promising photoanodes for solar water splitting due to their excellent chemical stability and appropriate bandgaps. However, in absorbers such as BiVO 4 , TiO 2 , α-Fe 2 O 3 , and WO 3 , charge carriers localize as small polarons or become trapped, leading t...
