Abstract
High efficiency small molecules were synthesized and characterized in solution-processed organic solar cells. These were star-shaped comprising of fused triphenylamine donating core, hexyl cyano acetate or methylene malononitrile accepting edges, and alkyl-substituted therthiophene bridge unit, exhibiting a noteworthy power conversion efficiency of 4.18% in solar cell device from bulk-heterojunction films with PC71BM.
