| Abstract: | Photoelectrochemical studies were carried out on [MnMoO2(NCS)(Ox)3(H2O)2] {Ox=8‐quinolinol} complex in aqueous dimethylformamide medium in a Honda cell. The system developed a maximum potential of 335 mV when exposed to visible light at 30°C and was found to be reversible. The photogalvanic behaviour has been further investigated by varying the pH, temperature and photosensitizers. When a temperature difference between the illuminated and dark half‐cells was maintained, the system generated 410 mV at 60°C. A solid‐state galvanic cell, developed using the complex mixed with tetraethylammonium perchlorate (TEAP), showed a maximum voltage of 25 mV. A sandwich galvanic cell, constructed from transparent tin oxide‐glass/complex/platinum, developed a maximum photovoltage of 88 mV when irradiated with a tungsten halogen lamp.
