Abstract

Four new alternating copolymers of naphthodifuran and quinoxaline have been developed. With the bandgap as low as 1.2 eV, polymers exhibited extended absorption to 1200 nm. Their potential in bulk heterojunction solar cells was evaluated. With device optimization, triazoloquinoxaline based polymers contributed the highest power conversion efficiency of 0.84%.
