| titleOfInvention | Diketopyrrolopyrrole unit-containing polymer, preparation method of diketopyrrolopyrrole unit-containing polymer and solar cell device |
| abstract | The invention discloses a diketopyrrolopyrrole unit-containing polymer. The diketopyrrolopyrrole unit-containing polymer has a structural formula shown in the patent specification, and in the structural formula, R1 represents C1-C20 alkyl, R2 represents C1-C20 alkyl and n represents an integer of 10-100. The diketopyrrolopyrrole of the diketopyrrolopyrrole unit-containing polymer has the advantages of strong absorbency and photochemical stability. Through alkyl chain modification on the N atom, a spectral absorption range is broadened and a band gap is decreased. Carbazole is a heterocyclic compound having a rigid plane biphenyl structure, has high heat stability and high hole mobility and is a good hole transport unit, and through introduction of the carbazolyl group into the main chain of the diketopyrrolopyrrole-based polymer, the problem of low efficiency of the existing solar cell device is solved. The invention also provides a preparation method of the diketopyrrolopyrrole unit-containing polymer and a solar cell device adopting the diketopyrrolopyrrole unit-containing polymer. |
