ROLE OF DYE PHOTOSENSITIZER AND SURFACTANT IN SOLAR ENERGY: A REVIEW

Abstract

Renewable energy sources are becoming imperative due to the high population, high demand energy and depletion of fossil fuels. The solar cells play important role in this regard. The third generation of solar cell has semiconductor electrode, dye, electrolyte, surfactant and counter electrode components. Among all of the components, dyes and surfactant perform a primary role in absorbing solar energy and converting it to electrical energy and storage capacity. The efficiency of working cells absolutely depends on the type of substance used as dye and surfactant.
