| titleOfInvention | A Class of D-π-A Passivation Molecules Using Benzotricarbazole as Donor in Perovskite Solar Cells |
| abstract | The invention provides a D-π-A-type molecule with benzotricarbazole as a donor, and also provides a D-π-A-type molecule with benzotricarbazole as a donor used as a passivating agent in In the defect passivation of perovskite thin films, the carboxyl groups on it can interact with lead ions, so as to passivate the unbonded lead ions in the lattice and reduce their recombination of photogenerated carriers. Moreover, the photosensitizing dye itself contains a large conjugated system, which is beneficial to the transport of photogenerated carriers in the perovskite, thereby improving the photoelectric conversion efficiency of the device. In addition, the deprotonation of the carboxyl group on it can passivate the methylamine defect in the perovskite film, and more alkyl chains in the molecule also improve the hydrophobicity of the perovskite film, effectively improving the battery's performance. Water and oxygen stability. After passivation, the optoelectronic properties of the device were significantly improved, and the photoelectric conversion efficiency (PCE) increased from 17.31% to 19.84%. |
