Abstract

Two wide-bandgap copolymer donors, W4 and W5, based on mono-fluorine- and mono-alkoxyl-substituted benzene units were developed. W4 and W5 were synthesized from cheap and commercially available starting materials. Organic solar cells based on W4 and W5 gave decent power conversion efficiencies of up to 15.25%.
