Abstract
A solid polymer electrolyte (SPE) photoelectrochemical cell, semiconductor-metal/SPE/Pt, is proposed as a new device to convert solar energy to electrical and/or chemical energy. The photoelectrochemical characteristics of TiO2-Pt/SPE and TiO2-Au/SPE were studied as well as those of the whole cell systems TiO2-Pt/SPE/Pt and TiO2-Au/SPE/Pt. By above bandgap energy illumination of the TiO2-metal side, negative photovoltage and anodic photocurrent were observed, as reported at TiO2 electrodes. In whole cell systems, i.e., TiO2-Pt/SPE/Pt and TiO2-Au/SPE/Pt, the conversion of light to electricity was achieved without using electrolyte solutionKeywords
