摘要

The present invention relates to a method for manufacturing a multi-junction solar cell, and a multi-junction solar cell manufactured by same, and comprises: a first step for forming a light absorption layer above a substrate for epitaxial growth; a second step for forming a back contact electrode above the light absorption layer; a third step for removing the substrate for epitaxial growth from the light absorption layer, and a fourth step for forming a front contact electrode above the light absorption layer on the side where the substrate for epitaxial growth has been removed, wherein the light absoprtion layer is formed with N sub-cells (N is a natural number greater than or equal to 2) having different absorption wavelengths from each other, and each sub-cell is joined via a tunnel junction to form a multi-junction.
