Photochemical energy conversion studies in systems containing methylene blue

The behaviour of photogalvanic cells containing methylene blue with various reducing agents has been examined. Appreciable potentials and currents have been detected. the power conversion efficiency of an EDTA-methylene blue photogalvanic cell has been estimated to be ±0.04 per cent. the storage of light energy in iron-methylene blue and EDTA-methylene blue systems has been studied.
