摘要

将Ullazine结构基元引入到聚合物主链或侧链中，分别与吡咯并吡咯二酮（DPP）、2

5-双（三甲基锡）噻吩共聚得到了二元共聚物PB和三元共聚物PT，分别利用凝胶渗透色谱和热重分析表征了聚合物的分子量和热稳定性，并研究了聚合物的光物理、电化学和光伏性能.基于共聚物PB和PT作为电子给体材料的聚合物太阳能电池器件测试结果表明，二元共聚物PB由于具有较低的能级水平从而获得较高开路电压，而侧链含Ullazine结构基元的三元共聚物PT具有更宽的吸收光谱和更高的空穴迁移率，获得了更高的短路电流和能量转换效率.

Abstract

Polymer solar cells (PSCs) based on the conjugated polymers as donor material have attracted considerable attention because of their various advantages such as lightweight

solution processability

flexibility and low-cost. Ullazine is an interesting multiring compound with conjugated plane and effective intramolecular charge transfer (ICT). In this study

the bipolymer PB and terpolymer PT were designed and synthesized by introducing an ullazine unit into the main chain or side chain of the conjugated polymer

by copolymerizing with diketopyrrolopyrrole (DPP) or 2

5-bi(trimetyltin) thiophene. The molecular weight was measured by gel permeation chromatography (GPC) and the thermal property was investigated with thermogravimetric analysis (TGA). The number-average molecular weight (

) and polydispersity index (PDI)were 2.8×10

and 1.7 for PB

7.6×10

and 2.1 for PT. The polymers PB and PT showed high decomposition temperatures (

5% weight loss) of 431 and 432 ℃

respectively. The photophysical

electrochemical

and photovoltaic properties of the two polymers were studied systematically. In diluted CHCl

solution

the bipolymer PB exhibited two absorption bands at 300-450 nm and 500-800 nm

and compared with PB

the terpolymer PT showed wider absorption bands and a red-shifted one to 900 nm. The HOMO and LUMO energy levels of the polymers PB and PT were determined to be-5.22 eV/-3.73 eV and-4.99 eV/-3.61 eV

respectively. The bulk heterojunction PSCs were fabricated with a device structure of ITO/PEDOT:PSS(~40 nm)/polymer:PC

BM(~100 nm)/LiF(0.5 nm)/Al(~80 nm) and measured under100 mW cm

-2

AM 1.5G illumination. As a result

polymer solar cells based on bipolymer PB: PC

BM blends (3% DIO additive) exhibited a low PCE of 0.88% (

=3.37 mA cm

-2

=0.79 V

FF =0.33)

and the PSC based on terpolymer PT exhibited a double PCE of 1.54% (

=6.63 mA cm

-2

=0.61 V

FF =0.38)

due to its wider absorption spectra and higher hole mobility in comparison with thebipolymer PB.
