چکیده انگلیسی
Inverted organic solar cells by bulk-heterojunctions were fabricated using TiO2 and ZnO as electron extraction layers. Electrospray deposition was applied to fabricate trilayer structures with thin donor and acceptor layers sandwiching bulk-heterojunction layers. Comparing to single layer devices, trilayer devices show significantly enhanced stability in device performances under continuous illumination in air. Conventional structure devices with Al as electron extraction layer were also compared showing how the improvement achieved with the inverted architecture is surprisingly higher. Our results, on a basis of 4Â h of continuous operations, show how combining inverted device architecture with trilayer configuration is a viable approach in achieving highly stable organic solar cells with 70% retainment of the initial PCE to be compared to the 13% in the case of direct trilayer BHJ.
