A Facile Planar Fused Ring Electron Acceptor for As Cast Polymer Solar Cells with 8.71% Efficiency.
A planar fused ring electron acceptor (IC C6IDT IC) based on indacenodithiophene is designed and synthesized. IC C6IDT IC shows strong absorption in 500 800 nm with extinction coefficient of up to 2.4 x 10(5) M( 1) cm( 1) and high electron mobility of 1.1 x 10( 3) cm(2) V( 1) s( 1) The as cast polymer solar cells based on IC C6IDT IC without additional treatments exhibit power conversion efficiencies of up to 8.71%
