Manganese-molybdenum-diethyldith MnMoO_2(Et_2dtc)_4(H_2O){Et_2dtc = diethyldithiocarbamate} complex has exhibited reversiblephotogalvanic behaviour in aqueous dimethylformamide medium whenstudied in a Honda cell. The photogalvanic behaviour has been furtherinvestigated by varying the PH, temperature and photosensitizers. UV,visible and sunlight were used as the radiation sources. A maximumpotential of 345 mV was obtained at 80 deg. C in visible light. Thesystem was found to be reversible for several cycles. Aphotoelectrochemical cell was constructed by coupling a chargednickel electrode with the complex electrode which incorporates theexperimental compound in acetylene black on a nickel substrate. Amaximum potential of l.08 V with 80 μA current was obtained whenirradiated with tungsten lamp.
