THICK FILM TYPED CIGS SOLAR CELL AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A thick film CIGS solar battery and a manufacturing method thereof are provided to improve the property of a bottom electrode by having the bottom electrode of a single layer structure or a multi-layer structure. CONSTITUTION: A CIGS solar battery comprises a substrate(12), a bottom electrode(14) which is laminated on the upper side of the substrate, and a photoelectric transformation layer(16) of CIGS composition. The bottom electrode is composed of a single layer having one or more compositions selected among Ni, Au, Pt, and Pd. The bottom electrode is composed of a first bottom electrode layer and a second bottom electrode layer. The first bottom electrode layer is close to the bottom surface of the second bottom electrode layer. The second bottom electrode layer is close to the bottom surface of the photoelectric transformation layer.
