Abstrakt: Cadmium sulfide (CdS) were synthesised directly in the active layer of solar cell by mixing regioregular poly (3-hexylthiophene-2,5-diyl) or P3HT with stearic acid, and exposed to hydrogen sulfide gas. The exposure times to hydrogen sulfide gas were varied and the isotherm of P3HT:Stearic acid obtained show that the presence of cadmium ions in the subphase changes the gas-liquid-solid transformation profile. UV-Vis-NIR results indicated that exposure to hydrogen sulfide gas created CdS particles resulting in wider absorption spectra. The exposed P3HT:SA active layer exhibit high resistance that affects short circuit current density and open circuit voltage of the solar cells device.
