Boosting Solar Cell Efficiency: Enhancing Dye-Sensitized Solar Cell Performance with Carbon Quantum Dots and Titanium Dioxide Nanostructures from Sri Lankan Ilmenite.

ABSTRACT: In dye-sensitized solar cells (DSSCs), the performance of commercially available TiO2 (P25, Degussa) is restricted by a low surface area and insufficient particle connectivity, resulting in hindered optoelectronic performance. This study presents an environmentally friendly and sustainable method for synthesizing TiO2 nanoparticles (NPs) using Sri Lankan ilmenite as a raw material. Additionally, carbon quantum dots (CQDs) are synthesized from coconut shells through a one-step hydrothermal carbonization process, providing a green synthesis process for these carbon-based nanomaterials. The study focuses on the performance of CQD-integrated DSSCs, where the photoelectrode is composed of TiO2 NPs. Photovoltaic properties of ruthenium-based DSSCs were evaluated under standard illumination condi
