Polymer photovoltaic devices based on poly (2. methoxy-5-(2. -ethyl-hexyloxy)-1.4-phenylene vinylene) (MEH- PPV) with three weight-average molecular weights (Mw) have been fabricated with the device structure of ITO/PEDOT/ MEH-PPV/Ca/Ag, and the effect of the molecular weight on photovoltaic properties has been investigated. The experi- mental results show that the high molecular weight of MEH- PPV leads to low series resistance (Rs) and high short-circuit current. The low molecular weight of MEH-PPV leads to high shunt resistance (Rsh) and high open-circuit voltage. When the molecular weight is 6×1.5, the highest power con- version efficiency was observed.

针对目前本体异质结有机太阳能电池活性层使用的给-受体(D-A)共聚物,研究对D-A给体材料的选取是设计高效有机太阳能电池的关键问题。本文分别选取了1.种D单元和A单元,采用第一性原理密度泛函方法,研究了D、A单元及其相应共聚物结构和能隙的变化。结果表明:噻吩环稠合时噻吩环的个数、噻吩环与苯环稠合时苯环的个数都可以有效地调制能隙的大小;同时结构中噻吩环上S原子的位置对带隙也有一定影响。在此基础上,选取噻吩并[3,4-b]噻吩D2.双噻吩锗D6和吡咯并吡咯二酮A4为单体的三种带隙值较小的聚合物,研究了三种高短路电流给体材料P_1.PDTG-PT)、P_2.PNTz4T)、P_3(DPPTT-T)的电子结构特性。通过分析其分子链构象、Bader电荷转移和形成能,表明它们是高短路电流有机太阳能电池D-A型给体材料的理想选择。本研究为设计高短路电流有机太阳能电池D-A型给体材料提供了有价值的指导。
