Abstract

We demonstrate a new solution-processed electron transport layer (ETL), zinc oxide doped with cesium carbonate (ZnO:Cs₂CO₃), for achieving organic photovoltaics (OPVs) with good operational stability at ambient air. An OPV employing the ZnO:Cs₂CO₃ ETL exhibits a fill factor of 62%, an open circuit voltage of 0.90 V, and a short circuit current density of -6.14 mA/cm² along with 3.43% power conversion efficiency. The device demonstrated air stability for a period over 4 weeks. In addition, we also studied the device structure dependence on the performance of organic photovoltaics. Thus, we conclude that ZnO:Cs₂CO₃ ETL could be employed in a suitable architecture to achieve high-performance OPV.
