Novel high performance asymmetrical squaraines for small molecule organic solar cells with a high open circuit voltage of 1.12 V

Abstract

An asymmetrically substituted squaraine ASQC bearing a 9-carbazyl substituent exhibits an extremely deep HOMO energy level of −5.46 eV and a relatively low bandgap of 1.65 eV, hence renders solution-processed organic solar cells with an impressive Voc of up to 1.12 V and a PCE of 2.82%.
