Heterojunction organic solar cell based on flexible substrate

摘要: 研究了基于柔性基板的有机薄膜太阳能电池，实验以聚3，4-乙撑二氧噻吩/聚苯乙烯磺酸盐作为阳极修饰层，1,4-亚苯基亚乙烯基（MEH-PPV）材料作为给体层以及富勒烯（C60）材料作为受体层制备异质结柔性有机太阳能电池。实验结果表明：增加阳极修饰层，虽然会阻挡光的吸收，但是可以大幅度地提高短路电流、开路电压、填充因子和能量转换效率4个参数。并发现MEH-PPV受体层的厚度对有机太阳能电池的性能有较大影响，当受体层厚度为90 nm时能量转换效率达到最大,为1.29%。

Abstract: Organic thin film solar cells based on flexible substrate were studied, which were prepared by using poly (3, 4-ethylenedioxythiophene): poly (4-styrenesulfonic acid) (PEDOT: PSS) as an anode modification layer, poly (2-methoxy, 5-(2-ethylhexyloxy)-1, 4-phenylene vinylene) (MEH-PPV) as a donor layer and fullerene (C60) as an acceptor layer. The results show that, the anode modification layer increases the short-circuit current density, open-circuit voltage, fill factor and power conversion efficiency of cells apparently although it may block the light absorption. The thickness of the acceptor layer also influences the cells performance. A maximum power conversion efficiency of 1.29% has been achieved by employing 90 nm-thick MEH-PPV layer.-
