Abstract

A novel-small molecular acceptor with electron-deficient 1,3,5-triazine as the core and perylene diimides as the arms is developed as the acceptor material for efficient bulk heterojunction organic solar cells with an efficiency of 9.15%.

Keywords: 1,3,5-triazine; non-fullerene acceptor; perylene diimide (PDI); polymer solar cells.
