Abstract
A significant effort is presently underway to improve the efficiency of limited sustainable energy devices. Dye-sensitized solar cells (DSSCs) are one of the most efficient and promising photovoltaic technologies. Tomato and strawberry syrups were used as natural sensitizers of anatase-based nanostructured TiO2 and coated ITO conducting glass to create a generic method for the fabrication of natural dye-sensitized solar cells. The remarkable value of voltage and current was noticed by using a sample preparation method. In addition, CuO thin-film solar cell has been fabricated using DC sputtering to compare with the DSSC solar cells. The low voltage and current values are observed for CuO solar cells, whereas, DSSC solar cells show a good value of efficiency as 1.25 × 10−6 % and 0.14 × 10–6 % for tomato and strawberry syrups respectively, under 775 W/m2 (Sunlight intensity).
