摘要:

以苯并三噻吩共聚物(BTT-BTz)为给体材料, 具有不同能级结构的富勒烯衍生物为受体材料, 通过共混方式制备光敏薄膜, 并研究受体材料的能级结构对光伏
器件开路电压(Voc)、 短路电流(Jsc)、 填充因子(FF)和电池效率(PCE)的影响. 结果表明: 当IC60BA为电子受体材料时, 器件的
Voc=1.06 V, 但Jsc较低, 使得PCE仅为1.49%; 当PC60BM和PC70BM 为受体材料时, Voc分别为0.86 V和0.81 V, 但Jsc较高, 使得PCE分别为3.22%和5.06%.

Abstract:

The energy level of the electron acceptor plays an important role in bulk heterojunction solar cells. A conjugated polymer BTT-BTz  as electron donor and fullerene derivatives PC70BM, PC60BM and IC60BA as acceptor with different energy levels was studied, and the influence of the acceptor energy level on the opencircuit voltage (Voc) , shortcircuit current density (Jsc), fill factor (FF) and power conversion efficiency (PCE) were investigated. The BTTBTz/IC60BA based device exhibited a high Voc of 1.06 V, but the poor PCE of 1.49% due to the lower Jsc. Although the Voc of the devices based on BTTBTz/PC60BM and BTTBTz/PC70BM is decreased, they displayed promising efficiencies of 322% and 5.06%.

Key words: solar cell, copolymer; bulkheterojunction
