Abstract
In dye-sensitized solar cells, the working electrode is frequently made of the semiconductor TiO2 (DSSC). TiO2 is utilized in two different forms: transparent paste and nano powder. In this study, TiO2 and a transparent sort of paste were used to fabricate DSSCs with success. To fabricate the DSSC, transparent TiO2 paste 18 NR-T was placed in the furnace Carbonite 1100 heating process with three different holding times. 10 minutes, 20 minutes, and 30 minutes at 500 °C were the different holding times employed. Ipomoea aquatica Forsk is the source of natural colouring. Keithley 2620A and UV-Vis Spectrophotometer Lambda 25 were used for the I-V test and the absorbance test, respectively, for DSSC characterization. According to the characterization results, the efficiency was 5.5 x 10-2 per cent. At the same time, the absorbance test found absorption peaks in the wavelength ranges of 400–440 nm and 640–680 nm for each watercolour dye.
