The application of polymer solar cells requires the realization of high efﬁciency, high stability,
and low cost devices. Here we demonstrate a low-cost polymer donor poly[(thiophene)-alt-
(6,7-diﬂuoro-2-(2-hexyldecyloxy)quinoxaline)] (PTQ10), which is synthesized with high
overall yield of 87.4% via only two-step reactions from cheap raw materials. More impor-
tantly, an impressive efﬁciency of 12.70% is obtained for the devices with PTQ10 as donor,
and the efﬁciency of the inverted structured PTQ10-based device also reaches 12.13%
(certiﬁcated to be 12.0%). Furthermore, the as-cast devices also demonstrate a high efﬁ-
ciency of 10.41% and the devices exhibit insensitivity of active layer thickness from 100 nm to
300 nm, which is conductive to the large area fabrication of the devices. In considering the
advantages of low cost and high efﬁciency with thickness insensitivity, we believe that PTQ10
will be a promising polymer donor for commercial application of polymer solar cells.
