In this research, we focused on designing electrode materials that increase the light-harvesting efficiency of photoanodes. Our experimental report presents a new, economical method for producing high-surface-area transition-metal (TM)- doped TiO2 nanocrystals (NCs) for DSSCs. A Silver nitrate (AgNO3)- doped titanium oxide (AgNO3-TiO2) was successfully synthesized using the Doctor Blade method and effectively utilized as a photoanode in the fabrication of a dye-sensitized solar cell (DSSC) to study the effect of the dopant on the dye. The solvent method was used to extract the chlorophyll pigment. The absorption study of the sensitized photoanode was characterized using a UV-Vis spectrometer. The DSSC was assembled and tested for photoelectric properties using a solar simulator. The result revealed a photoelectric conversion efficiency PCE (η) of 0.16 %; Voc of 0.452 V, Isc of 0.692 mA/cm2, Vmax of 0.324 V, Imax of 0.501 mA/cm2, Pmax of 0.162 mW/cm2, and FF of 0.52 were obtained. The coated FTO glass with a TiO2 metal oxide surface, doped with silver at 0.2 molar concentration, has been shown to provide more surface area for dye adsorption and to extend visible light absorption.
