Role of Redox-Couples for Generation of Electrical Energy in Dye Sensitized Solar Cell

Anoop Singh Meena

Abstract


Growing concern of rise in fossil fuel prices and environmental degradation have led to the world’s interest in renewable energy sources. Out of various renewable energy sources, solar energy is freely available and commercially viable source for electrical energy generation. It is one of the most resourceful sources of energy for the future.The conversion of solar energy into electrical energy can be done by DSS cells. DSS cell is based on dye sensitization technique, in which electron ejection by the photosensitized dyes is randomly transferred to a vacant site where they will be localized for a period of time that depends on the trap site depth relative to the conduction bond.Electron may also be transformed to the oxidized dyes. In this research article, we studied on the role of redox-couple forgeneration of electrical energy in DSS cell. The results of cell are observed in terms of photopotential, photocurrent, fill factor, conversion efficiency, and cell performance.
