The current-voltage (I-V) studies for p-SiC in KOH and n-SiC in Na2SO3 in a
two-electrode configuration indicated that SiC-based photoelectrochemical
systems can be a possibility for water splitting. With illumination there i
s appreciable photocurrent generation at the semiconductor-electrolyte inte
rface, which correspond to water splitting to form hydrogen and oxygen at t
he respective electrodes. The C-V analysis gave an idea about the hat-band
potential and carrier concentration. (C) 2000 International Association for
