Abstract

The present invention relates to a ligand-exchanged inorganic perovskite quantum dot thin film and a solar cell comprising the same. The inorganic perovskite quantum dot thin film provided in one aspect of the present invention is capable of more effective ligand exchange by directly inserting the organic ligand ion-based salt generating organic ligand ions, and the thin film can be used to prepare solar cells with high power conversion efficiency. Therefore, the thin film of the present invention can contribute to the commercialization of perovskite quantum dot solar cells in the future.
