The dye-sensitized solar cells were fabricated using different natural dyes extracted from the Ixora flower, Pongame leaves, Neem leaves, sunflower, and Almond fruit. TiO2 nanoparticle has been prepared via the solvothermal method. The prepared samples were characterized by structural properties of X-Ray Diffraction, Field Emission-Scanning Electron Microscope, EDAX, and High Resolution-Transmission Electron Microscope, Optical properties of UV–Visible and Fourier Transform Infrared Spectroscopy studies, and Conductivity studies of EIS spectra. The average crystallite size and structure of prepared particles is determined by the XRD, and FTIR confirmed the functional groups present in the prepared samples. And also band gap values were calculated using UV–Visible spectroscopy. The resistance and conductivity of the samples were identified using the EIS spectra. The effect of natural dye extract from chlorophyll and anthocyanin pigment group was investigated for the performance of J-V characterization. The efficiency of almond extract of solar cells is found to be greater than that of the other four extracts sensitized solar cells. •The tertagonal structure of ZnO nanoparticles was synthesized via the solvothermal method.•The FESEM of the ZnO nanoparticles exhibits spherical shaped particles.•The electrochemical impedance analysis shows a good bonding behaviour for the almond fruits.•From the J-V curve, the efficiency of almond based TiO2 device given the best efficiency better than the other natural photo-anode devices.
