| titleOfInvention | A method for preparing light-absorbing layer thin film of perovskite solar cell |
| abstract | The invention discloses a method for preparing a light absorbing layer film of a perovskite solar cell, which comprises preparing a mixed material solution of perovskite and conjugated organic molecules; dropping the mixed material solution of perovskite and conjugated organic molecules on the surface of a clean substrate, and starting Spin coating, after the mixed material solution of perovskite and conjugated organic molecules is evenly covered on the surface of the substrate, drop the perovskite anti-solvent, and continue the spin coating; after the spin coating is completed, a protective film is attached to the surface to slow down the solvent After volatilizing, heating and annealing the substrate, removing the protective film and cooling to room temperature naturally, the synergistic growth of perovskite nanocrystals and nanowire films can be obtained on the substrate. In the process of preparing the perovskite light-absorbing layer, the invention adopts the mixed material of perovskite and conjugated organic molecule together with the surface protective film to synergistically grow perovskite nanocrystals and nanowires, so as to obtain interpenetrating network structure and large crystal grains. sized perovskite films. |
