Abstrakt: The influence of the light intensity on the photoelectroreduction of CO2was investigated at a p-GaP photocathode in 0.1 mol dm−3KHCO3aqueous solution. The faradaic efficiencies for the formation of HCOO−and H2were strongly affected by the light intensity. The maximum faradaic efficiency for HCOO−production was close on 70%. A mechanism of variation of the efficiencies with light intensity was discussed.
