Abstract
Photogalvanic cells are a type of solar cell that converts solar energy into electrical energy by the direct electrochemical process. Photogalvanic cells are made up of four main components i.e. reductant, surfactant, dye, and micelles. The reductant is a substance that donates electrons to another substance. In a photogalvanic cells the reductant is typically an organic molecule, such as glucose or ascorbic acid. The surfactant is a substance that lowers the surface tension of a liquid. In a photogalvanic cells, the surfactant helps to form micelles, which are spherical aggregates of surfactant molecules. The dye is a substance that absorbs light and emits photons of a different color. In a photogalvanic cells, the dye absorbs sunlight and uses the energy to excite electrons from the reductant. The micelles are spherical aggregates of surfactant molecules. In a photogalvanic cells, the micelles help to concentrate the dye and reductant molecules, which increases the light absorption efficiency and electron transfer processes. In present, photogalvanic cells are under consideration for better performance but they have more potential to achieve more efficient and cost-effective way to convert solar energy into electricity than traditional silicon solar cells.
