摘要：
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 J(SC) of up to 11.03 mA cm(-2) and an excellent PCE of 4.29%.
