Dye Sensitized Solar Cell using natural dye as light harvesting sensitizer

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. TiO 2  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.
