Title:
METHOD FOR PRODUCING LAMINATE AND METHOD FOR PRODUCING PEROVSKITE SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2020/121991
Kind Code:
A1
Abstract:
Provided is a novel method for producing a laminate that serves as an electron transport layer and an optically transparent electrode layer of a perovskite solar cell having, in the following order, an optically transparent electrode layer, an electron transport layer, a perovskite crystal layer, a hole transport layer, and a current collecting layer. The method involves forming a titanium oxide layer that serves as the electron transport layer on a member that serves as the optically transparent electrode layer by utilizing said member for cathode polarization in a treatment liquid containing a Ti component.
