摘要：
The utilization of two-dimensional graphitic carbon nitride (C3N4) nanosheets as a cathode interfacial layer (CIL) in inverted polymer solar cells (PSCs) is demonstrated. The device with C3N4 as a CIL exhibited a remarkable improvement in power conversion efficiency, indicating that C3N4 can effectively modify the BHJ/ITO interface to facilitate efficient electron collection. Our results indicate that the solution exfoliated C3N4 is a new and promising electron transport material for solution processed organic optoelectronic devices.
