Ligand exchange of perovskite quantum dots and a solar cell devices manufactured using the same

摘要

It relates to an inorganic perovskite quantum dot thin film in which surface ligands are exchanged and a solar cell including the same, In an inorganic perovskite quantum dot thin film provided in one aspect of the present invention, not only does the ligand exchange more effectively, but also photoelectric conversion using the thin film by directly putting an organic ligand ion-based salt directly generating organic ligand ions. Since it is possible to manufacture highly efficient solar cells, it can make a great contribution to commercialization of perovskite solar cells in the future.
