Abstract
Disclosed are a high density CIS thin film and a method of manufacturing the same, which includes coating CIS nanopowders, CIGS nanopowders or CZTS nanopowders on a substrate by non-vacuum coating, followed by heat treatment with cavities between the nanopowders filled with filling elements such as copper, indium, gallium, zinc, tin, and the like. The high density CIS thin film is applied to a photo-absorption layer of a thin film solar cell, thereby providing a highly efficient thin film solar cell.
