The readily availability of energy is the center on which all technology relies. The solar energy, being the mother of energy need, to be harness by various applications on which Dye-Sensitized Solar Cells (DSSCs) is a very cost-effective way to tap into this natural renewable energy. This study explores the viability of Bougainvillea flower dye extracts as sensitizers in DSSCs for efficient solar energy conversion. The study focuses on extracting dye compounds from Bougainvillea flowers and integrating them into DSSCs. The efficiency of these solar cells is evaluated through various parameters, including performance, stability, and photovoltaic characteristics. The energy conversion efficiencies of Bougainvillea flower were found out to be 0.13%. This phenomenon arises from the interaction between the carbonyl and hydroxyl groups of the anthocyanin molecule in dye extracts and the surface of the TiO2 porous film.
