摘要
In the present paper, we report the studies on perovskite (CH3NH3PbI3): Zinc Oxide (ZnO) bulk heterojunction (BHJ) photoactive layer (with two different ZnO concentrations) based solar cells fabricated under ambient air. ZnO and NiOx layers are used as the electron and hole transport layers respectively. The typical cell parameters of CH3NH3PbI3: ZnO BHJ solar cells have been calculated and analysed in comparison to that of solar cell fabricated with pristine perovskite (CH3NH3PbI3) based photoactive layer. The best performing solar cell (CH3NH3PbI3: ZnO; 1 mg/ml) has demonstrated highest power conversion efficiency (PCE) of 8.97% and retained 83.82% of its original value after 30 days under ambient air.
