esign, Synthesis And Photovoltaic Properties Of Conjugated Copolymers Based On Fluorinated Benzothiadizole
有机太阳能电池相对于传统的无机半导体太阳能电池具有成本低、制备工艺简单、柔性、重量轻、可制备大面积器件等优点，备受人们的关注。给体材料的吸收光谱、能级以及空穴迁移率等都是影响光伏器件能量转化效率的主要因素，本文主要从拓宽材料的吸收光谱、调节能级、提高迁移率等方面出发，设计合成了两种基于氟化苯并噻二唑结构的共轭聚合物PIDT-DTBT和PIDT-DTffBT。其中聚合物PIDT-DTffBT具有较高的空穴迁移率和较窄的带隙1.90 eV，基于PIDT-DTffBT/PC71BM(1:1，w/w)的光伏器件在标准光强照射下，能量转化效率为1.39%。
ompared to conventional inorganic semiconductor solar cells, Organic photovoltaics (OPVs) have caught people's attention recently since they have the advantages of low cost, simple manufacture process, flexibility, light weight and could be made a large area devices. The main factors of affecting the power conversion efficiency of the photovoltaic devices including the absorption spectrum of the materials, the energy level and the hole mobility. This paper is focusing on design and synthesis of new photovoltaic materials with broader absorption spectrum, appropriate energy level, higher hole mobility. Finally two conjugated copolymers based on fluorinated benzothiadizole as the acceptor unit, PIDT-DTBT and PIDT-DTffBT were designed and synthesized. The band gap of polymer PIDT-DTffBT were 1.90 eV. The power conversion efficiency of the photovoltaic device based on PIDT-DTffBT/PC71BM (1:1, w/w) were 1.39%.
