Abstract

A novel asymmetrical squaraine ASQ-5 bearing indoline as an end capper exhibits a low bandgap of 1.43 eV and a broad absorption band in the Vis-NIR region of 550–850 nm in thin films, hence renders solution-processed organic solar cells with an impressive Jsc of up to 11.03 mA cm−2 and an excellent PCE of 4.29%.
