| titleOfInvention | A kind of tin-based perovskite solar cell and preparation method thereof |
| abstract | The invention belongs to the technical field of preparation of novel thin-film solar cells, and specifically discloses a tin-based perovskite solar cell and a preparation method thereof. In the method, a tin-based perovskite thin film is prepared by adding phenethylamine bromide to a tin-based perovskite precursor solution and adopting one-step spin coating. The additive helps to improve the crystalline quality of the film, improve the morphology, reduce internal defect states and reduce non-radiative recombination. In addition, the matched band structure formed by the absorption layer and the charge transport layer prepared by this technique enhances the carrier transport ability. The corresponding photoelectric conversion efficiency of the tin-based perovskite solar cell device reached 14.65% and remained above 90% of the initial value after being placed for 4800 hours. The above data show that the addition of phenethylamine bromide to the precursor solution is an effective preparation method to improve the photoelectric conversion efficiency and stability of tin-based perovskite cells. |
