Yongsheng Liu, Yang (Michael) Yang, Chun-Chao Chen, Qi Chen, Letian Dou, Ziruo Hong, Gang Li and Yang Yang Solution-Processed Small Molecules Using Different Electron Linkers for High-Performance Solar Cells Advanced Materials 25
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 Voc of 0.85 V, a Jsc of 10.79 mA cm−2 and a notable FF of 67.1% are achieved with T3/PC71BM blend based devices using polydimethylsiloxane as additive.
