带有9-咔唑基取代基的不对称取代的方酸菁ASQC表现出-5.46 eV的极深的HOMO能级和1.65 eV的相对低的带隙，因此使得溶液处理的有机太阳能电池具有高达1.12 V的令人印象深刻的Voc和2.82%的PCE。
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%.
