With NiO:WO3 layer, the efficiency can be improved from 3.2% to 4.1% and showed 80% of the maximum efficiency retained over 60 days. © 2011 IEEE.[SDGs]SDG7Maximum Efficiency; Mixed metal oxide; Moisture barriers; Polymer Solar Cells; Photovoltaic effects; Solar cells; Metallic compoundsconference paper10.1109/PVSC.2011.6186158
