Dye Sensitized Solar Cell using natural dye as light harvesting sensitizer

Abstract

Due to the availability, non-toxicity and cost-effectivity, natural dyes are becoming popular day by day. In this study, dye-sensitized solar cells (DSSCs) were fabricated using natural dyes containing anthocyanins extracted from pomegranate, blackberry and beet route. TiO2 film on FTO glass prepared by doctor blade method was employed as photoanode. The structural and morphological properties of photoanode was studied using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM), respectively. The extracted dye absorption was evaluated by UV-Vis-NIR spectroscopy. The fabricated cells have efficiency in the range of 0.015 – 0.042% which has been measured by sun simulator.
