Title:
How to manufacture a perovskite solar cell
Document Type and Number:
Japanese Patent JP6352223
Kind Code:
B2
Abstract:
The purpose of the present invention is to solve problems such as the optical degradation of sensitizing dye which is a concern of a dye-sensitized solar cell, the volatilization of electrolyte solution, low durability due to leakage, and high manufacturing cost which is a concern in silicon solar cells and compound-semiconductor solar cells. Provided is a perovskite solar cell in which a negative electrode, a hole block layer, a perovskite layer, a hole transport layer, and a positive electrode are sequentially formed. The perovskite solar cell is characterized in that: the negative electrode comprises at least one type of material selected from a group including metal titanium, titanium alloy, metal titanium subjected to surface treatment, and titanium alloy subjected to surface treatment; and the positive electrode is irradiated with light.
