AI Technical Summary
Technical Problem
Perovskite solar cells lack specific proposals for improving durability in environments prone to salt damage.
Method used
A method for manufacturing perovskite solar cells involves forming a perovskite sheet with a perovskite crystal structure and a compound represented by the chemical formula M2+ 1-x M3+ x (OH)2 (NO3 - ) x/n ⋅ mH2 Layered double hydroxide, which is converted to a chloride ion (Cl - ) to enhance durability in salt-damaged environments.
Benefits of technology
The proposed method allows perovskite solar cells to be used effectively in environments where salt damage is expected, improving their durability and service life.

Abstract
In order to provide a method for producing a perovskite solar cell that can be used even in an environment in which salt damage is predicted, this method for producing a perovskite solar cell includes a step for forming a coating layer by applying, on a perovskite sheet formed of a plurality of layers including a perovskite crystal structure, an adsorption material having a layered double hydroxide represented by chemical formula: M2+ 1-xM3+ x(OH)2(NO3 -)x / n·mH2O (where M2+ represents a divalent metal, M3+ represents a trivalent metal, and n represents a natural number).
