Evidence has been obtained for hot-electron injection from illuminated p-GaP photocathodes into nonaqueous electrolyte containing anthracene as the electron acceptor. The position of the conduction-band edge at the electrolyte interface has been unequivocally established from Mott- Schottky plots in the dark and under illumination; no band-edge movement occurs during the experiment. The observed supraband-edge reduction of anthracene occurs with a hot-electron energy of 0.9 eV.
