The new polymer Nap-SiBTz is designed and synthesized for fabrication of non-fullerene organic solar cells (NFOSC) device application. Nap-SiBTz comprised of 4,8-bis(5-(6-((2-hexyldecyl)oxy)naphthalen-2-yl)thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene (BDT) as donor and 5,6-difluoro-2-(6-(1, 1,1,3,5,5,5-heptamethyltrisiloxan-3-yl)hexyl)-4,7-bis(4-octylthiophen-2-yl)-2H-benzo[d][1,2,3] triazole (BTA) as acceptor unit. The Nap-SiBTz was synthesized by Stille polymerization. Further, their thermal, photophysical, electrochemical properties are systematically investigated. It has been successfully utilized to fabricate NFOSC. The optimized device showed a maximum power conversion efficiency (PCE) of 5.01% and also indicate the importance of appropriate polymer for the development of high-performance NFOSC for practical applications. |
