Photoelectrochemical characterization of SiC

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 is appreciable photocurrent generation at the semiconductor–electrolyte interface, which correspond to water splitting to form hydrogen and oxygen at the respective electrodes. The C–V analysis gave an idea about the flat-band potential and carrier concentration.
