Abstract
The invention relates to nitrile substituted quinacridone compounds and application thereof in an organic solar cell. The compounds provided by the invention are quinacridone derivatives using nitrile substituted quinacridone as a basic structural skeleton or quinacridone derivatives using nitrile substituted 2, 9-thiophene quinacridone as a basic structural skeleton. The compounds provided by the invention can be used for preparing an organic solar cell with one or more than one active layer, and at least one layer of the active layers contains one or more than one compound provided by the invention. The active layer can be a light absorbing layer and/or a migrating layer and/or a charge injection layer. The filling factor of the bulk heterojunction solar cell device prepared by using the compounds provided by the invention is higher, and the spectral response range reaches 700nm; and the bulk heterojunction solar cell device is solution-processable, which is beneficial to industrial production.
