Title: COMPOUND SEMICONDUCTOR SOLAR CELL AND METHOD OF MANUFACTURING THE SAME
Abstract:
A compound semiconductor solar cell and a method of manufacturing the same are disclosed. The method for fabricating a compound semiconductor solar cell comprises forming a first mask layer on a front surface of a compound semiconductor layer of a second region which is a region other than a first region where the front electrode is to be formed; forming a seed metal layer on the front surface of the compound semiconductor layer of the first region and on the first mask layer of the second region; removing the seed metal layer over the first mask layer and the first mask layer; removing a part of the compound semiconductor layer of the second region from the front surface of the compound semiconductor layer by using the seed metal layer of the first region as a mask; forming a second mask layer on the compound semiconductor layer of the second region; forming an electrode metal layer on the seed metal layer not covered by the second mask layer; and removing the second mask layer.
