Natural dyes are cost effective substitute of costly synthetic and metal dyes used in Dye-sensitized solar cells (DSSCs). In this study DSSCs based on natural dye rutin and its iron complex have been fabricated using quasi-solid state polymeric electrolyte and characterized in terms of photovoltaic properties. Nano crystalline TiO2 was synthesized in the lab and analysed through Raman spectroscopy. The UV-VIS absorption spectra of TiO2 thin film before and after sensitization with rutin and its iron complex were recorded. The UV-VIS absorption spectra of dyes solution were also recorded for the same range of wavelength. Increased absorption was observed for rutin iron complex as compared to pure rutin in both forms. Different photovoltaic parameters i.e. short circuit current density, open circuit voltage, fill factor and power conversion efficiency were obtained using J-V curve of these devices. The power conversion efficiencies of rutin and Fe-rutin based devices are found to be 0.21% and 0.41% respectively. Around 95% increment in power conversion efficiency was observed after iron complexation of rutin.
