中文摘要：
采用溶胶-凝胶法（Sol-Gel），通过强碱水解锌盐溶液合成了ZnO的纳米粒子和纳米棒，并用旋涂的方法制备了纳米ZnO与MEH—PPV（聚苯乙烯撑）复合的异质结光电器件。通过TEM、XRD、UV、PL等手段考察了不同的纳米粒子后处理方法以及不同的纳米晶形状对器件薄膜形貌和光电性能的影响。制备的器件性能在纳米ZnO质量分数为75％时达到最高，此时短路电流Isc达到2．52mAcm^-2、开路电压Voe为0．8V、填充因子FF为46．3％、光电能量转换效率η为1．00％。此结果接近目前国内外所报道的纳米ZnO，共轭聚合物共混型器件的最高水平（目前报道最高的能量转换效率为1．60％）。
英文摘要：
The ZnO nanocrystal by Sol-Gel method, and fabricated a new hybrid solar cell from ZnO nanocrystal and conjugated polymer MEH-PPV have been synthesized. The effect of Nanocrystal＇s post-treatment and morphology on the devices performance have been studied through TEM,XRD,UV,PL. The devices demonstrates the best optoelectronic performance with 75% of ZnO nanocrystal in the composite film. The best device conversion efficiency reaches 1.00%.
