ABSTRACT:
Photoelectrolysis of water by solar radiation to produce hydrogen is achieved using semiconducting thin film electrodes. The cell comprises (a) an electrode comprising at least one thin film semiconducting layer disposed on a substrate, each layer having a bandgap which ranges from about 1.3 to 4.0 eV; (b) a counter-electrode; (c) an electrolyte disposed between the thin film semiconducting electrode and the counter-electrode; (d) external bias means between the electrode for biasing the electrode with from 0 to about 1 V; and (e) means for collecting hydrogen produced.
