Abstract
Official abstract text for this publication.
To manufacture a thin film compound solar cell which can improve the adhesive property of electrodes even when being provided with a base material, and which prevents the base material from being separated. A cell main body configured by laminating a plurality of compound semiconductor layers is formed on a substrate. A rear surface electrode 7 is formed on the cell main body, and a rear surface film 8 as the base material is formed on the rear surface electrode 7 . A reinforcing material 9 is attached on the rear surface film 8 . The substrate is separated from the cell main body, and the cell main body is mesa-etched. A surface electrode 13 is formed on a contact layer 3 after the etching. The reinforcing material 9 is separated, and the surface electrode 13 is annealed. The formed thin film compound solar cell is separated into a plurality of solar cell elements.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a thin film compound solar cell having a cell having a compound semiconductor layer in which at least one PN junction is formed, the method comprising: a process of forming a compound semiconductor layer comprising at least one PN junction on a side of a substrate; a process of forming a rear surface electrode on a surface of the compound semiconductor layer; a process of forming a base material made of a polyimide film by appl…
