Dye Sensitized Solar Cell With Natural Dye Extract from Beetroot

Solar cells have attracted increasing attention over the last decades. One of the emerging technologies in solar field is Dye Sensitized Solar Cell (DSSC). Dye Sensitized Solar Cells have been extensively used because they offer the advantages of low cost, lower toxicity, environmental friendly and low weight. DSSC is the most promising new generation system for photovoltaic technology. TiO2 photo electrode is prepared by doctor blade technique and is sensitized using the 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, the DSSC is fabricated. The UV and Current-Voltage characteristic has been studied and also the solar power conversion efficiency is found.
