将硫化镉纳米棒与偶联聚合物聚[2-甲氧基-5-（2′-乙基己氧基）-1,4-苯基乙烯]（MEH-PPV）混合，研究了杂化太阳能电池的光电性能。通过多孔氧化铝模板，电化学沉积在Ti衬底上垂直生长CdS纳米棒。复合层的吸收光谱与各材料吸收光谱的叠加相同。混合使MEH-PPV薄膜的光致发光信号减弱。与垂直排列的CdS纳米棒组合后，MEH-PPV太阳能电池的能量转换效率从0.0012%提高到0.60%左右。
Optoelectronic properties of hybrid solar cells were investigated by mixing cadmium sulfide nanorods with a conjugated polymer, poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). CdS nanorods were grown vertically on Ti substrates by electrochemical deposition through a porous alumina template. Absorption spectrum of the composite layer was the same as the superposition of the absorption spectrum of each individual material. The photoluminescence signal from MEH-PPV film was reduced as a result of the mixing. The energy conversion efficiency of MEH-PPV solar cell improved from 0.0012% to about 0.60% when combined with the vertically aligned CdS nanorods.
