中文摘要:

用由 C60 衍生物组成的混合异质接面[6,6 ]-phenyl-C61-butyric 酸甲基酉旨(PCBM ) 并且(3-hexylthiophene )(P3HT ) poly 作为费用搬运人转移媒介代替 I3 ?/I?氧化还原作用电解质,一节新奇灵活敏化染料的太阳能电池(DSSC ) 被制作。红外线的系列和紫外可见的系列的描述证明 PCBM/P3HT 异质接面为 P3HT 在可见、近的红外线的光为 PCBM,而且吸收在紫外光有不仅吸收,它为 DSSC 拓宽光电的反应范围。太阳能电池的表演上的 PCBM/P3HT 集体比率的影响被讨论。不到 100 mW 厘米 ?(AM 1.5 ) 2 模仿了太阳的照耀,灵活太阳能电池完成 1.43% 的 light-to-electric 精力变换效率, 0.87 V 的开的电路电压, 3.0 妈厘米的短路电流密度 ? 2 并且充满 0.54 的因素。

英文摘要:

Using blend heterojunction consisting of C60 derivatives [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) and poly(3-hexyl- thiophene) (P3HT) as charge carrier transferring medium to replace 13-/1-redox electrolyte, a novel flexible dye-sensitized solar cell (DSSC) is fabricated. The characterization of infrared spectra and ultraviolet-visible spectra shows that the PCBM/P3HT heterojunction has not only the absorption in ultraviolet light for PCBM, but also the absorption in visible and near infrared light for P3HT, which widens the photoelectric response range for DSSC. The influence of PCBM/P3HT mass ratio on the performance of the solar cell is discussed. Under 100 mW cm-2 (AM 1.5) simulated solar irradiation, the flexible solar cell achieves a light- to-electric energy conversion efficiency of 1.43%, open circuit voltage of 0.87 V, short circuit current density of 3.0 mA cm-2 and fill factor of 0.54.
