Abstract
Polymer solar cells (PSCs) provide special opportunities for low-cost, printable, light-weight, flexible,
and portable energy sources. For the past few years, a great advance to improve the efficiency of
polymer solar cells has been achieved owing to development of new semiconducting polymers,
understanding of organic semiconductor physics and advancement in the device optimization
including interface engineering. As a result, the power conversion efficiency (PCE) has continuously
increased to its current value over 8%. Nevertheless, further development of PSCs is still needed for
commercialization, which requires the PCE higher than 10%. To enhance the PCE, many approaches
has been proposed: (i) synthesis of low bandgap conjugated copolymers to harvest the solar spectrum
more effectively, (ii) synthesis of semi-conducting polymers with deep HOMO levels to enhance V0 c,
(iii) synthesis of planar conjugated polymers to afford high hole mobility, (iv) synthesis of new
fullerene derivatives as acceptor material, and others.
