我们描述了一种基于氧化锌和共轭聚合物poly[2-methoxy-5-(3‘，7’-dimethyloctyloxy)-1，4-phenylene-PPV复合薄膜的体-异质结混合聚合物太阳电池的新方法。旋涂二乙基锌作为氧化锌的前驱体和MDMO-PPV在40%湿度的普通溶剂中，在110℃下进行热处理，可以得到结晶的氧化锌与MDMO-PPV紧密混合的薄膜。光致发光和光诱导光谱表明，这些杂化复合薄膜的光激发导致了聚合物作为施主到作为受主的氧化锌的快速和长寿命的电荷转移。采用氧化锌前驱体法制备了空气质量为1.5(AM 1.5)的杂化聚合物太阳电池，能量转换效率为1.1%。与类似的基于非晶态二氧化钛的杂化聚合物太阳能电池相比，这种新方法的性能提高了五倍。
We describe a new method towards bulk-heterojunction hybrid polymer solar cells based on composite films of zinc oxide (ZnO) and a conjugated polymer poly[2-methoxy-5-(3',7'-dimethyloctyloxy)-1,4-phenylene vinylene] (MDMO-PPV). Spin-coating diethylzinc as a ZnO precursor and MDMO-PPV from a common solvent at 40 % humidity and annealing at 110 degrees C provides films in which crystalline ZnO is found to be intimately mixed with MDMO-PPV. Photoluminescence and photoinduced spectroscopy demonstrate that photoexcitation of these hybrid composite films results in a fast and long-lived charge transfer from the polymer as a donor to ZnO as ato be obtained n acceptor. Using the ZnO-precursor method, hybrid polymer solar cells have been made with an estimated air-mass of 1.5 (AM 1.5) energy conversion efficiency of 1.1 %. This new method represents a fivefold improved performance compared to similar hybrid polymer solar cells based on amorphous TiO2.
