Abstract

Solar cells have attracted increasing attention over the last two decades. One of the emerging technologies in the solar field is Dye-sensitized Solar Cell (DSSC). Dye-sensitized Solar Cells have been extensively used owing to their advantages of low cost, lower toxicity, environmental-friendliness and low weight. DSSC is the most promising new generation system for photovoltaic technology. In this work, TiO₂ photoelectrode was prepared by Doctor Blade technique and was sensitized using beetroot extract as a natural sensitizer. The sensitizer is an essential component to absorb sunlight to its extent and convert the incident photons into electric current. With the counter-electrode and electrolyte solution, DSSC was fabricated. UV and Current-Voltage characteristics have been studied and solar power conversion efficiency has been determined.
