Abstract
Current‐voltage measurements are reported for heavily p‐type Si electrodes in NaCl solution. The zero current voltage depends logarithmically on light intensity, indicating that photoelectrolytic devices are solar cells in series with electrolytic cells. The catalytic efficiency of the electrode is enhanced by illumination, but Si is a poor hydrogen electrode, probably because of its surface oxide.Keywords
