摘　　要：采用一步水热法制备了用于聚合物太阳能电池受体材料的核壳结构碳银复合材料(Ag@C),并以聚3-己基噻吩(P3HT)为给体材料,旋涂制备P3HT∶Ag@C复合膜。通过场发射扫描电子显微镜、热重分析仪、透射电子显微镜及电化学工作站,对Ag@C的形貌、热稳定性和能级结构进行表征分析,并用荧光分析仪和紫外分光光度计对复合膜的光学性能进行表征分析。结果表明,Ag@C具有良好的热稳定性且与P3HT能级相匹配,满足作为聚合物太阳能电池受体材料要求;与纯P3HT薄膜相比,复合膜发生荧光猝灭现象,光生激子在复合膜界面处可得到有效分离;光谱吸收范围变宽,增强了对太阳光的吸收。Core shell Ag@C composite used as acceptor materials in polymer solar cell was mildly synthesized under hydrothermal conditions.The composite films were fabricated by spin coating method with poly（3hexylthiophene）（P3HT）acting as donor materials.The morphology,thermal stability,and energy level of the Ag@C were investigated by field emission scanning electron microscopy,thermogravimetric analyzer,transmission electron microscopy,and electrochemical workstation.The optical performance of the composite films was analyzed by fluorescent spectrometry and ultraviolet visible spectrophotometry.The results show that the products demonstrate good thermal stability,matching with the energy level of P3 HT,which could satisfy the requirements as the acceptor materials in the polymer solar cell.Compared with the pure p3 HT film,fluorescence quenching effectively separates excitons at the interface of composite films and broader absorption spectrum intensifies the absorption of sunlight.
