 A new ternary strategy was developed for fabricating efficient and photo-stable inverted organic photovoltaics, OPVs. This approach combines a bulk heterojunction, beach-shea, blend with a fullerene self-assembled monolayer, C60 SAM, which is vertically arranged. The ternary blend is shown to be more effective than the binary blends, as evidenced by higher power conversion efficiencies and better photo stability.
