Abstract
The photochemical properties of vacuum deposited films and of sintered and doped iron(III) oxide have been studied. From the wavelength dependence of the photopotentials we know that photo-activity of the electrochemical cell with the iodine/iodide redox couple starts at the same wavelength, 600–650 nm, as the absorption of light and the photoconductivity of vacuum deposited films. Open circuit potentials of about 400 mV have been observed with the visible radiation from a 150 W xenon lamp. In neutral solution photocorrosion was too small to be observed.
