| titleOfInvention | A method for enhancing the performance of perovskite solar cells based on dye interfacial layers |
| abstract | The invention relates to a method for improving the performance of a perovskite solar cell based on a dye interface layer, comprising: (1) attaching a first charge transport layer on a transparent conductive substrate; (2) coating a perovskite precursor solution on a first charge transport layer; On top of a charge transport layer, a perovskite thin film is obtained by spin coating, and then anti-solvent is added dropwise to promote crystallization, followed by thermal annealing to obtain a perovskite light-absorbing layer; (3) spin-coating thiophene on the perovskite light-absorbing layer ‑The quinoline type diheterocyclic azo dye precursor solution is heated and annealed to obtain a dye interface layer; (4) a second charge transport layer is attached on the dye interface layer, and the transparent conductive substrate and the second charge transport layer are respectively Attach the top electrode. By adding a dye interface passivation layer on the perovskite light absorption layer, the dye exists on the surface and grain boundary of the perovskite to passivate the grain boundary defects, suppress the non-radiative recombination of the interface, and improve the quality of the perovskite thin film. Enhanced efficiency and stability of perovskite solar cells. |
