| titleOfInvention | Diketopyrrolopyrrole-base polymer, and preparation method and application thereof |
| abstract | The invention belongs to the field of solar cell materials, and discloses a diketopyrrolopyrrole-base polymer which has the following structural formula, wherein R1 and R2 are respectively a C1-C20 alkyl group, and n is a whole number ranging from 10 to 50. In the diketopyrrolopyrrole-base copolymer, the DPP has the advantages of high absorptivity, high photochemical stability and the like; the DPP can modify the alkyl chain through N atoms; when the lengths of thiophenes connected to the 3 site and 6 site of the DPP are increased, the absorption range becomes wider, and the band gap becomes smaller; and all of the properties can enhance the energy conversion efficiency of the organic solar cell. |
