| titleOfInvention | A method for optimizing lead-free perovskite solar cell thin films |
| abstract | The invention discloses a method for optimizing a lead-free perovskite solar cell thin film. When preparing the active layer, the perovskite precursor solution is first spin-coated on the hole transport layer, and the spin-coating time is 50 s. The diethyl ether solution doped with chiral mandelic acid was drop-coated for 12 s, and then annealed to obtain the active layer; the oxygen ion in the hydroxy acid molecule in mandelic acid has lone pair electrons, which can form coordination with metal ions bond, slow down and control the perovskite crystallization process, and because mandelic acid is a reducing agent, it can inhibit the oxidation of divalent tin, thereby improving the crystallinity of the perovskite film. The combination of the two phases can significantly improve the film quality. The power conversion efficiency of perovskite-based solar cells; the circularly polarized light emission of the chiral material mandelic acid itself will enhance the absorption of the perovskite film, thereby effectively improving the power conversion efficiency of the device; and mandelic acid is mainly extracted from plants , widely sourced and safe to use. |
