Abstract
A series of polymers based on electron-deficient benzimidazole segments and electron-rich benzodithiophene segments for polymer solar cells was designed and synthesized. The polymer solar cell devices with benzimidazole based polymers achieved power conversion efficiency (PCE) close to 1%. This work implies that polymers based on benzimidazole segment can achieve high PCE through structural modification of the polymers.
