As a promising two-dimensional nanomaterial with outstanding electronic, optical, thermal, and mechanical properties, graphene has been proposed for many applications. In this Progress Report we summarize and discuss comprehensively the advances made so far for applications of graphene in organic photovoltaic (OPV) cells, including that for transparent electrodes, active layers and interfaces layer in OPV. It is concluded that graphene may very likely play a major role in new developments/improvements in OPVs. The future studies for this area are proposed to focus on the following: i) improving the conductivity without comprising the transparency as a transparent electrode material; ii) controlling the sheet sizes, band structure and surface morphology for use as a electron acceptor material, and iii) controlling and improving the functionalization and compatibility with other materials as interface layer material.
作为一种具有出色的电子、光学、热学和力学性能的有前途的二维纳米材料，石墨烯已经被提出用于许多应用。在本进展报告中，我们全面总结和讨论了迄今为止在有机光伏（OPV）电池中应用石墨烯的进展，包括透明电极、活性层和界面层。结论是，石墨烯很可能在 OPV 的新发展/改进中发挥重要作用。该领域的未来研究建议集中在以下方面：i）提高导电性而不牺牲透明性作为透明电极材料；ii）控制薄片尺寸、带结构和表面形态，用作电子受体材料，以及 iii）控制和改善功能化以及与其他材料的兼容性作为界面层材料。
