| Abstract |
In order for organic solar cells to fully mature from research and development into cost effective products, a continuous improvement in solar cell efficiency must be achieved. A fundamental comprehension of design principles of new polymer materials are necessary to push this area forward. We synthesized a series of conjugated random copolymers with a backbone of 5,6-difluoro-2,1,3-benzothiadiazole moieties and studied the effect of the polymer structure on photovoltaic properties. We demonstrated that modification of the polymer backbone affected the energy levels and the morphology of polymer/fullerene blend films, resulting in power conversion efficiencies (PCEs) of 7~10%. Moreover, such high solar cell performances are effectively realized in a large area and so resulting devices achieves PCEs over 9%. This work shows the effect of fine-tuning of the chemical structure on solar cell performance. |
