Abstract
A method of manufacturing a light absorbing layer for a solar cell by performing thermal treatment on a specimen configured to include thin films of one or more of copper, indium, and gallium on a substrate and element selenium, includes steps of: heating a wall of a chamber up to a predefined thin film formation temperature in order to maintain a selenium vapor pressure; mounting the specimen and the element selenium on the susceptor at the room temperature and loading the susceptor in the chamber; and heating the specimen in the lower portion of the susceptor and, at the same time, heating the element selenium in the upper portion of the susceptor.
