Photoelectric Performance of Organic Dye Sensitized Solar Cell on Various Thicknesses of TiO2 Paste

Dye sensitized solar cells (DSSCs) were fabricated with various thicknesses of TiO2 paste using the aqueous extract of dragon fruit pulp as photosensitizer. The thickness of TiO2 paste was based on number of layers (2, 3, 4 and 5 layers) of Scotch tape on the conductive substrate. The fabricated DSSC was placed at a distance of 10 cm from halogen light bulb (100 W), and the photoelectric performance of the DSSC was measured after 10 minutes of the exposure period. Results showed that the characteristics of solar cell by using aqueous extract of dragon fruit pulp with three layers of Scotch tape (0.372 mm) was found to produce the best electrical performance with Voc, Isc, FF and efficiency were 245mV, 0.0271mA, 0.1190, and 0.2182 %, respectively. The efficiency increased with increasing thickness of TiO2 paste to some extent.
