Solar energy conversion
has nowadays attracted research interests
of the community, wherein conjugated polymers (CPs) become a class
of workhorses on photon-to-electron and photon-to-fuel conversion
studies. In recent years, exciting breakthroughs have been made in
these multi-interdisciplinary fields, with the assistance of the intrinsic
flexibilities on tuning optoelectronic, mechanical and structural
properties of CPs. In this review, we summarize the recent notable
development of CPs in polymer solar cells, perovskite solar cells,
and photocatalysts, wherein CPs function well as light-capture and
conversion components for polymer solar cells and photocatalysts as
well as charge extraction materials for perovskite solar cells. By
analyzing the principles, status, and structural-properties of these
areas, we outline the design strategies and perspectives of CPs for
further advancing solar energy conversions.
