다국어 초록 (Multilingual Abstract)

In this study, We modified ZnO electron transport layer (ETL) with water/alcohol soluble polymer and controlled the surface property of the organic-inorganic hybrid ETL (m-ZnO). The morphology of photoactive layer and interfacial contact between ETL and photoactive layer were enhanced by introducing m-ZnO. We fabricated inverted organic photovoltaic (IOPV) devices by introducing m-ZnO. For the reference device (ITO/ZnO/photoactive layer/MoO₃/Ag), the open circuit voltage (Voc), short circuit current (Jsc), fill factor (FF) and power conversion efficiency (PCE) were 0.717 V, 16.3 mA/cm², 64.7% and 7.2%, respect respectively. By introducing m-ZnO, the IOPV with ITO/m-ZnO/photoactive layer/MoO3/Ag, exhibited enhanced performances which were 0.737 V, 18.5 mA/cm², 65.7% and 9.0%.
