摘要

聚合物太阳能电池(PSC)由共轭聚合物给体和富勒烯衍生物受体的共混膜(活性层)夹在ITO 透明导电玻璃正极和低功函数金属负极之间所组成

具有制备过程简单、成本低、重量轻、可制备成柔性器件等突出优点

近年来成为国内外研究前沿和热点。当前研究的焦点是提高器件的光电能量转换效率

而提高效率的关键是高效共轭聚合物给体和富勒烯衍生物受体光伏材料。本文将重点介绍化学所近年来在新型共轭聚合物给体和富勒烯衍生物受体光伏材料方面的研究进展

包括带共轭支链的宽吸收两维共轭聚合物、带吸电子基团取代基的具有较低HOMO能级的共轭聚合物、宽吸收和具有较低H OMO 能级的给体-受体(D-A)共聚物给体光伏材料、以及茚双加成C

衍生物ICBA 和茚双加成C

衍生物IC

BA 受体光伏材料等。基于这些给体光伏材料制备的PSC 最高能量转换效率达到7.59%

是聚合物光伏材料迄今文献报道最高效率之一。使用我们的新型受体ICBA 使基于聚3-己基噻吩(P3H T)的PSC 的能量转换效率超过了7%

是基于P3HT 光伏器件能量转换效率文献报道最高值。

Abstract

Polymer solar cells (PSCs)are composed of a blend film (active layer) of a conjugated polymer donor and a fullerene derivative acceptor sandwiched between a transparent ITO positive electrode and a low workfunction metal negative electrode. PSCs have become the hot research field in recent years

due to their unique advantages of simple fabrication

low cost

light weight and capability to be fabricated into flexible devices. The present research focus is to improve their photovoltaic power conversion efficiency (PCE)

and the key aspects for improving PCE are high efficiency photovoltaic materials. In this paper

I will mainly introduce the recent research progress of Institute of Chemistry

Chinese Academy of Sciences (ICCAS) on the new conjugated polymer donor and fullerene derivative photovoltaic materials

including the donor materials of two-dimensional conjugated polymers with conjugated side chains

conjugated polymers with electron-withdrawing substituents for lower HOMO energy levels

D-A copolymer with broad absorption and lower HOMO energy levels

and the acceptor materials of indene-C

bisadduct (ICBA) and indene-C

bisadduct. The highest PCE of the PSCs based on the conjugated polymer donor materials reached 7.59 %

which is one of the highest efficiencies reported in literatures so for. The PSCs based on P3HT as donor and our ICBA as acceptor showed PCE higher than 7%

which is the highest efficiency for the PSCs based on P3HT.
