Method of preparing reprocessed perovskite compound, reprocessed perovskite compound prepared thereby, perovskite device and solar cell comprising the same

Abstract

A method of preparing a reprocessed perovskite compound, a reprocessed perovskite compound prepared thereby, and a perovskite device and a solar cell including the same. The preparation method can reduce the manufacturing cost of products in which a perovskite device is used by restoring a degraded perovskite compound, and can minimize environmental pollution associated with disposal of perovskite compounds containing heavy metals. Furthermore, high-quality perovskite devices and solar cells can be provided by using the reprocessed perovskite compound prepared by the preparation method.
