Comparative Performances of Natural Dyes Extracted from Mentha Leaves, Helianthus Annuus Leaves, and Fragaria Fruit for Dye-Sensitized Solar Cells

During the last four centuries, there have been extensive research activities looking for green and clean sources of energy instead traditional (fossil) in order to reduce accumulation gases environmental pollution. Natural dye-sensitized solar cells (DSSCs) are one most promising types photovoltaic generating at a low cost. In this study, DSSCs were collected experimentally tested using different dyes extracted from Mentha leaves, Helianthus annuus Fragaria, mixture above extracts equal proportions as natural stimuli TiO2 films. The result show that was successfully turned into electricity. Additionally, based on mixtures showed better results than those single dyes. Efficiency (η) 0.714%, fill factor (FF) 83.3% cell area.
