摘要: 旋涂法和真空蒸发结合制备了MEH-PPV：PCBM体异质结和CuPc/C60有机小分子叠层有机太阳电池.测试结果表明： MEH-PPV：PCBM有源层和Ag中间层分别为50 nm和0.5 nm时，与同等厚度有源层的MEH-PPV：PCBM体异质结器件和CuPc/C60小分子器件相比，叠层器件太阳能转换效率大大提高，达到了1.86%.

Abstract: A tandem solar cell, composed of a MEH-PPV:PCBM bulk heterojunction front sub-cell and a CuPc/PCBM small molecule back sub-cell, is fabricated by spin-coating and vacuum evaporating methods. Measurement results show that an optimal tandem solar cell with 50 nm MEH-PPV:PCBM active layer thickness and 0.5 nm Ag inter-layer thickness can be obtained with a power conversion efficiency of 1.86%. -
