Dye-Sensitized Solar Cells Fabrication Employing Natural Hues as Photosensitizing Substances

Dye-sensitized solar cells (DSSCs) are plausible alternative compared to the most traditional silicon-based solar cells, for its economical trait of conversion of photovoltaic energy. DSSCs were fabricated by depositing six natural dyes, which were extricated from Pomegranates, Beet, Eggplant, Red Amaranth leaves (Amaranthus Cruentus), Sunflower and Malabar spinach on optically transparent film of titanium dioxide. Studies on optical attributes of extricated natural dyes and photoelectrical characteristics of the assembled DSSCs were made and concluded that among all the six natural dyes Malabar Spinach seeds showed the highest current density and effective efficiency of converted solar energy.
