Fluorine substitution enhanced photovoltaic performance of a D-A 1-D-A2 copolymer
Artikel i vetenskaplig tidskrift, 2013
A new alternating donor-acceptor (D-A1-D-A2) copolymer containing two electron-deficient moieties, isoindigo and quinoxaline, was synthesized. The photovoltaic performance of this polymer could be improved by incorporating fluorine atoms into the quinoxaline units, resulting in an efficiency of 6.32%. This result highlights the attractive promise of D-A 1-D-A2 copolymers for high-performance bulk heterojunction solar cells. © 2013 The Royal Society of Chemistry.
