Abstract

A novel wide-bandgap polymer donor PBDTS-DTBTO, which shows an optical bandgap of 1.76 eV and a strong Π–Π interaction feature. Power conversion efficiency reached over 9% in the fullerene-free polymer solar cells (PSC) device By using a low-bandgap acceptor ITIC, indicating complementary absoprtion spectra for the donor and acceptor are of great importance for achieving a highly efficient fullerene-free PSC device. Additionally, the PSC devices fabricated by PBDTS-DTBTO:ITIC showed relatively small sensitivity to variations of the active layer thickness, and PCE equal to 8% could be achieved when the active layer thicknesses range from 50 to 200 nm, suggesting it is a promising candidate for further practical production study of fullerene-free PSC.
