Fabrication of TiO₂ based Dye-Sensitized Solar Cell using Nerium oleander as a sensitizer

Abstract

The globe has already started using renewable energy sources, mainly solar energy, to meet the rising need for energy. The Dye-Sensitized Solar Cell (DSSC), one of many varieties of solar cells, is now popular because of its low manufacturing cost and ability to function in low light. In this work, TiO2 and erbium-doped TiO2 are chosen as photoanode and Nerium oleander as a sensitizer. The photoanode materials are prepared by one-step microwave assisted hydrothermal method. These nanomaterials and sensitizer are characterized by various characterization techniques that show significant results. The designed DSSC is evaluated by the current-voltage properties study. The efficiency of the fabricated TiO2 and Er-doped TiO2 based DSSCs is found to be 0.95 % and 2.95 % respectively.
