Abstract

Due of their affordability and eco-friendliness, dye -sensitized solar cells (DSSC) are becoming more widely used as a yet strongly evolving strain of solar cells. We have examined the performance of dye-sensitized solar cells in this research through SCAPS-1D simulation. This model consisted of five layers FTO / TiO2/Rhamnus tinctoria dye/ liquid electrolyte/pt. The effect of ETM, HTM, and active layer thicknesses, working temperature, the affinity of ETL, and the interface between TiO2 and active layer on different parameters of the dye -sensitized solar cells (DSSCS) are studied. Experimental data was used to determine some of the study's input parameters. The density functional theory (DFT) computations were used to analyze the electronic characteristics. Each state's VOC, JSC, FF, and PCE are investigated. The obtained results are contrasted with those of experiments. An optimization process has been done on the configuration increasing the efficiency from 0.49 % up to 0.81 %.
