CIGS SOLAR CELL AND METHOD OF FABRICATING THE SAME

摘要

PURPOSE: A CIGS solar battery and a manufacturing method thereof are provided to maximize energy conversion efficiency by minimizing sunlight which is reflected from the surface of a window electrode layer. CONSTITUTION: A lower electrode layer is formed on a substrate. An optical absorption layer(30) is formed on the lower electrode layer. A buffer layer(40) comprises a plurality of protrusions. A window electrode layer(50) is unevenly bent on the buffer layer along the plurality of protrusions.
