Naphtho[1,2-b:5,6-b’]dithiophene-based conjugated polymer as a new electron donor for bulk-heterojunction organic solar cells |
| 초록 |
We report for the first time the synthesis and photovoltaic application of a Naphtho[1,2-b:5,6-b’]dithiophene (NDT) which is symmetrical, planar, π-conjugated, and rigidly fused potential semiconductor containing donor-acceptor conjugated copolymer. The combination of thiophene-bridge NDT building block with a quinoxaline acceptor unit results in a new copolymer that has an optical band gap of 1.77 eV, a HOMO level of -5.24 eV, and a hole mobility of 5.0x10-5 cm2V-1s-1. Preliminary characterization of the bulk-heterojunction solar cell device exhibits a PCE of around 1.5%. |
