The open-circuit photovoltage (V/sub oc/) generated at an n-Si electrode coated with a microscopically discontinuous platinum layer in a redox solution is increased by changing the redox potential of the redox couple toward the positive, until it reaches about 0.5 V, much higher than the V/sub oc/ (ca. 0.2 V) for an n-Si electrode coated with a continuous Pt layer. These results verify a theory proposed by us on the discontinuous metal coated semiconductor electrodes and open up a new approach to efficient photoelectrochemical solar cells.
