Organic molecules based on bisfluorothiophene units and their application as hole transport materials in perovskite solar cells |
| abstract |
The invention belongs to the technical field of organic functional materials. The invention discloses an organic molecule based on a bisfluorothiophene unit and its application as a hole transport material in a perovskite solar cell. A 3-fluorothiophene unit is selected as a central unit, Construction of molecular hole transport materials with electron-donor units (D)-planar fluorinated π-bridges-electron-donor units (D). Specifically, 3,3'-difluoro-[2,2'-thiophene] is symmetrically linked at both ends to bis(4-(methylthio)diphenyl)amine and bis(4-(methylthio)triphenyl) ) amine-based organic molecular materials (DFBT‑DPA‑MT and DFBT‑TPA‑MT), and used both materials as hole transport layers in planar perovskite solar cells. The planar perovskite solar cells based on DFBT‑DPA‑MT and DFBT‑TPA‑MT as hole transport layers can achieve energy conversion efficiencies exceeding 19%, respectively. |
