Abstract

The photogalvantic effect has been studied by relatively few people. Perhaps the largest contribution to the study of this effect has been by E. Rabinowitch while the Massachusetts Institute of Technology and terminated in 1940. At this time Rabinowitch indicated the possibilities in the utilization of solar energy by the photogalvantic effect (1). Presented here is a study of the effect using a modified form of the apparatus used by Rabinowitch. An attempt is made at explaining the results obtained, the advantages and disadvantages of the apparatus used and suggestions are given for improvement. A specific photogalvantic system of high efficiency containing a reversibly reducible organic dyestuff (thionine) together with an inorganic oxidation-reduction pair (Fe++/ Fe+++) was thoroughly investigated by E. Rabinowitch (4).
