摘要

Abstract

In this paper

a new D-A copolymer

PFDBCPDT

which consists of benzo-2

3-thiadiazole as acceptor units and cyclopentadithiophene and fluorene as donor units

was synthesized. The thermal

electrochemical

photophysical and photovoltaic properties of PFDBCPDT were studied. PFDBCPDT showed a low optical band gap of 1.84 eV

and relatively low HOMO level of −5.69 eV. The best device performance was obtained by PFDBCPDT/PC61BM (1:3) with 0.5 vol% DIO. The device exhibited a power conversion efficiency of 3.06%

with a relatively high open circuit voltage of 0.87 eV.
