Abstract

Dye sensitized solar cell (DSSC) is a third-generation solar cell based on photoelectrochemical processes that can convert solar energy into electrical energy with the help of a sensitizer as a light absorber and TiO₂ as a charge separator. The electrolyte is one of the components of DSSC in the form of a liquid containing an iodide/triiodide redox couple. A weakness of DSSC is that the electrolyte easily evaporates, resulting in low performance and durability. The addition of a fiber tissue layer between the working electrode and the counter electrode as an absorbent medium can reduce the evaporation rate of the electrolyte and improve the performance of the DSSC. This study aimed to investigate the performance of DSSC with the addition of a fiber tissue layer with varying hole sizes as an electrolyte-absorbing medium. The research consisted of three stages: DSSC structure preparation, DSSC layer arrangement and assembly, and DSSC measurement. The fiber tissue added in this study has square holes with varying sizes: 0 cm × 0 cm, 0.5 cm × 0.5 cm, 0.75 cm × 0.75 cm, 1 cm × 1 cm, 1.25 cm × 1.25 cm, 1.5 cm × 1.5 cm, and a control sample without fiber tissue. The parameters observed in this study include current and voltage characteristics, power calculation, fill factor, and DSSC efficiency. Based on the results, DSSCs with fiber tissue layers of varying hole sizes generally showed better performance compared to the control DSSC. The best performance was obtained from the DSSC with a fiber tissue layer having 1 cm × 1 cm hole size. The electrical characteristics obtained were: Voc: 608 mV, Isc: 96.4 µA, Vmax: 288 mV, Imax: 0.0634 mA, Pmax: 18.26 µW, Fill Factor (FF): 0.3355, and Efficiency: 0.0673%.
