Abstract
A new conjugated small molecule composed of dithienopyran and diketopyrrolopyrrole
(DTP-DPP) was synthesized. Since DTP-DPP has advantageous optoelectronic
properties for photovoltaic applications such as intense and broad light absorption, proper frontier
energy levels, high crystallinity, and high hole mobility, the devices fabricated from the blend with
PC71BM and P(NDI2OD-T2) exhibit high power conversion efficiencies of 6.88% and 4.82%,
respectively. This work demonstrates that DTP-DPP is a versatile electron donor compatible with both fullerene and nonfullerene acceptors for high performance SM-OSCs.
