photogalvanic cell is a cell ,which directly converts energy from the sun into electrical energy.
A photogalvanic cell is a type of electrochemical cell that generates electrical energy from light. It typically consists of a photoactive electrode, an electrolyte, and a counter electrode. When light is absorbed by the photoactive electrode, it initiates a chemical reaction that produces a potential difference and drives an electric current.
The importance of sunlight in bringing about not only photosynthesis in plants, but also other photochemicaleffects, is reviewed. More effort should be devoted to photochemical storage of the sun's energy without the living plant. There is no theoretical reason to believe that such reactions are impossible. Ground rules for searching for suitable solar photochemical reactions are given, and a few attempts are described, but nothing successful has yet been found. Future possibilities are suggested. Photogalvanic cells which convert sunlight into electricity deserve further research. Eugene Rabinowitch has been an active pioneer in these fields.
