Abstract

Conjugated acceptor-donor-acceptor small molecules using different electron linkers are designed, synthesized, and used in organic solar cells. All of these small molecules show high photoconversion efficiencies (PCEs), ranging from 3.18-6.15% under simulated AM 1.5G condition. A maximum PCE of 6.15% combined with a high Vocof 0.85 V, a Jscof 10.79 mA cm-2and a notable FF of 67.1% are achieved with T3/PC71BM blend based devices using polydimethylsiloxane as additive.
