| 제목 | Development of donor-acceptor type-based random copolymer for highly efficient polymer solar cells |
| 초록 | In recent years, as a result of development of novel low band gap donor polymer, the device characteristics of the polymer solar cells such as FF, Voc, and Jsc have shown dramatic increase and the solar cell efficiency has been achieved up to ~ 10%. To increase current density, the further broad absorption spectra to give a decisive effect on performance of devices should be basically required. Accordingly, we synthesized low band gap random copolymers included different monomers donor unit and acceptor unit, which have different absorption. In this work, we demonstrate the highly efficient polymer solar cells using two different novel low band gap polymers as donor materials in the photoactive layer. Also, the effects of two difference random copolymers on the device parameters such as FF, Voc, and Jsc were investigated. As a result, PCE of optimum polymer solar cells with random copolymers showed 5.9% and 7.71%, respectively. |
