| Abstract: | Improved efficiency of hybrid Al/Ca/P3HT:CISe:TiO2/PEDOT:PSS/ITO thin film solar cells was obtained by optimizing P3HT/CISe ratio. This study also investigated the effects of TiO2 content in the P3HT:CISe active layer, and altering annealing temperature conditions. The optimum TiO2 content and annealing temperature for solar cell efficiency is 25 wt.% and 150 °C, respectively. The optimal results for the open circuit voltages (VOC), short-circuit current density (JSC), fill factor (FF), and efficiency (η) of the prepared hybrid thin film solar cell were VOC = 0.335 V, JSC = 8.07 mA/cm2, FF = 52.75, and η = 1.425. |
