中文摘要：
石墨烯是由紧密堆积成二维蜂窝状晶格结构的单层sp2杂化碳原子构成的新型纳米碳材料，具有重要的理论研究和实际应用价值。本项目拟在前期工作基础上，首先实现石墨烯在尺寸、层数等微观结构方面的可控制备，并进行有机功能化方面的研究，以得到可溶液加工和能级可调控的功能化石墨烯材料；同时设计合成吸收光谱覆盖整个可见光区、具有高的载流子迁移率和能级可控的新型聚合物材料；研究石墨烯作为新的电子受体与已知经典给体材料或项目设计合成的新型给体材料共混或通过共价相连形成的分子内给体-受体杂化材料作为活性材料在有机光伏器件中的应用；研究基于石墨烯/聚合物的光伏器件中能量转化和传递机理和光伏效率的制约因素，以期得到稳定性良好，成本较低，和易大批量制备的且具有较高光电转化效率新型光伏活性材料；最后研究基于石墨烯的透明导电薄膜作为透明电极代替ITO在有机光伏器件中的应用，以期在有机光伏电池的结构和组成方面取得突破。
