A new structural design of interfacial materials aza[60]fulleroid was reported that promotes optimal contact between organic bulk heterojuctions (BHJs) with metal oxides. By facilitating effective π-conjugation between fullerene and aromatic addends the electronic coupling between fullerene and the underneath metal oxides (through conjugated anchors) could be enhanced. As a result, new interfacial modifiers with varied functionalities and energetics are found not only to be able to shift the WF of ZnO, but also mediate the electron extraction from BHJ to metal oxide ETL. In addition, it is possible that it can also optimize the phase evolution of the BHJ layer atop.
