Investigation of manganese-molybdenum-diethyldithiocarbamate complex as a potential system for solar energy conversion

Manganese-molybdenum-diethyldithiocarbamate [MnMoO2(Et(2)dtc)(4)(H2O)] {Et( 2)dtc = diethyldithiocarbamate} complex has exhibited reversible photogalva nic behaviour in aqueous dimethylformamide medium when studied in a Honda c ell. The photogalvanic behaviour has been further investigated by varying t he pH, temperature and photosensitizers. UV, visible and sunlight were used as the radiation sources. A maximum potential of 345 mV was obtained at 80 degrees C in visible light. The system was found to be reversible for seve ral cycles. A photoelectrochemical cell was constructed by coupling a charg ed nickel electrode with the complex electrode which incorporates the exper imental compound in acetylene black on a nickel substrate. A maximum potent ial of 1.08 V with 80 mu A current was obtained when irradiated with tungst en lamp. Copyright (C) 1999 John Wiley & Sons, Ltd.
