polymers prepared by microwave-assisted synthesis can achieve power
conversion efficiencies (PCEs) >7% in bulk-heterojunction solar cells
with phenyl-C61/71-butyric acid methyl ester (PCBM). In “as-cast”
PBDFTPD-based devices solution-processed without a small-molecule
additive, high PCEs can be obtained in spite of the weak propensity of
the polymers to self-assemble and form π-aggregates in thin films.
