Development of dye-sensitized solar cell (DSSC) using patterned indium tin oxide (ITO) glass: fabrication and testing of DSSC

Dye-sensitized solar cell (DSSC) is the third generation of solar cell which comprises of semiconductor electrode, counter electrode and electrolyte. It utilizes the advantage of the wide band gap semiconductor that sensitized to the light. This paper presents the fabrication of DSSC using natural dyes that extracted from mangosteen pericarp and maqui berry. Before depositing the semiconductor electrode, Titanium Dioxide (TiO₂), a pattern of lines on conductive side of Indium Thin Oxide (ITO) glass is developed using Krypton Fluoride (KrF) excimer laser RapidX 250 at AMBIENCE lab. For the analysis, the absorption of the dyes is compared by using UV-Vis spectrophotometer. While, the performance of the patterned DSSC in terms of fill factor, efficiency, current density is investigated by using digital multimeter. As the result, this paper proves that the efficiency of the patterned DSSC is improved for both of the dyes.
