Abstract
Properties of the p-InP-Pt- and p-Si-Pt-electrolyte junctions are compared by means of capacitance- and impedance measurements under hydrogen evolution conditions. Discontinuous metal coatings leed to high barriers and efficient charge transfer. The model of a Schottky-type solar cell in series to an electrochemical reaction step is confirmed by impedance data for both semiconducting materials and irrespective of deposition methods or electrolyte pH. Barrier heights and diode ideality factors are derived under photocurrent flow and current-voltage curves are given for H2-evolution and for a photoelectrochemical solar cell.
