| 摘 要： | 利用简单的低温工艺制备了纳米晶纤锌矿结构的ZnO,用高分辨透射电镜(HRTEM)、X射线衍射(XRD) 和光致发光(PL)技术进行了表征.利用纳米晶ZnO和共轭聚合物2.甲氧基.5.(3,7.二甲基辛氧基)对苯撑乙烯 (MDMO-PPV)制备了结构为ITO/PEDOT：PSS/ZnO：MDMO-PPV/A1的有机/无机复合体异质结太阳电池,作为 对比,同时制备了ITo/PEDOT：PsS/MDMo-PPV/Al结构的纯有机聚合物电池.实验结果表明,添加纳米晶ZnO 使其能量转换效率提高了约550倍.PL谱测试结果表明这是由于有高电子亲合能的ZnO提高了电子空穴对分离 的能力.另外,光伏性能的提高可能也与ZnO引起的电子传输能力的提高有关.此外,本文分析了ZnO：MDMOPPV体异质结电池性能低于传统电池的原因,并提出了进一步提高其性能的方法.
