摘　　要：利用光学近场激发与局域理论,通过光学仿真软件建立银/金方阵微纳结构理论模型,使用高分辨率光刻技术构建基于完美吸收体的聚合物/富勒烯太阳能电池结构,实现活性层对太阳光谱从紫外到近红外全波段光谱的完美吸收,提高了聚合物电池能量转换效率.设计和制备了结构上类似、彼此具备良好的"相容性"、在吸收光谱上互补的新型给体材料.与富勒烯受体材料混合制作三元体系的太阳能电池,以最大程度地匹配太阳光谱,该方法可以有效地提高器件对太阳光的响应能力,产生大量的光生载流子,大幅度地提高短路电流密度和开路电压.本文研究有望为获得新一代高效率、高稳定性的聚合物光伏器件提供参考.A theoretical model of Ag/Au micro and nano structure was established based on the optical near-field excitation and the local field theory by optical simulation software.The new structure of polymer/fullerene solar cells based on the perfect absorber are demonstrated by high resolution lithography technology,and the perfect all-optical wavelength absorption of the solar spectrum from the ultraviolet to near-infrared light is achieved in order to improve energy conversion efficiency of solar cells.At the same time,the new donor materials was designed and prepared which have similar structure,good ＂compatibility＂ and complementary absorption spectrum.The ternary solar cells were prepared which fabricated with two polymers as the electron donors blended with fullerene acceptor to maximize the matching of the solar spectrum.This method can effectively improve the response of the device to the sunlight,produce a large number of optical carriers,and greatly improve the short circuit current density and the open circuit voltage.Then the new polymer solar cells with high efficiency and high stability are expected.
