Polymer solar cells have drawn attention because of their advantages of light weight, easy to large-area fabrication, and low fabrication cost by the solution process. To improve the performance of devices, many researchers have been carried out including synthesis of new materials, optimization of fabrication processes and interfacial engineering. Among them, the interfacial engineering is one of the crucial strategies. GO was synthesized by hummer‘s method and was used as a hole transporting layer (HTL) in polymer solar cells. In this presentation, we report the properties of polymer solar cells with chemically modified GO. |
