The efficiency of photoelectrolysis with solar radiation can be greatly enhanced by using simultaneously illuminated n- and p-type electrodes. An energy level scheme for heterotype and homotype p-n photoelectrolysis cells is presented which explains the enhanced efficiency. Data are presented for the homotype n-GaP/p-GaP and the heterotype n-TiO/sub 2//p-GaP systems which support the energy model. H/sub 2/ and O/sub 2/ are produced in the n-TiO/sub 2//p-GaP cell without the need of an external anodic bias. (AIP)
