Comparison of Natural Dye-Sensitized Solar Cells and Polymer Efficacy

Harvesting energy from sunlight using photovoltaic technology is one of the most important research areas because of an ever increasing global energy need.Now a day’s study of dyes extracted from natural resources is the main concern for researchers. Application of natural dyes is a promising development in the field of this technology. Natural dyes are cutting down high cost of metal complex sensitizers and also replacing expensive chemical synthesis process through simple extraction process. Natural dyes are abundant easily extractable safe material causes no environment threat. These can be extracted from flowers petals leaves roots and barks in the form of anthocyanin carotenoid flavonoid and chlorophyll pigments.This book discusses development of three natural dyes and their effect on various performance parameters of dye sensitized solar cell.
