Patent ID: 8779282

Claim:
A solar cell apparatus comprising: a. substrate; a back electrode layer on the substrate; a light absorbing layer on the back electrode layer; and a front electrode layer on the light absorbing layer, wherein an outer peripheral side of the back electrode layer is aligned on a plane different from a plane of an outer peripheral side of the light absorbing layer, wherein an outer peripheral side of the front electrode layer is disposed on a side different from a side where the outer peripheral side of the back electrode layer is aligned, wherein the outer peripheral side of the light absorbing layer is aligned on a same plane with the outer peripheral side of the front electrode layer, wherein the outer peripheral side of the light absorbing layer is disposed outside the outer peripheral side of the back electrode layer, wherein the outer peripheral side of the front electrode layer is disposed outside the outer peripheral side of the back electrode layer, and wherein the apparatus comprises a recess formed in the back electrode layer between the light absorbing layer and a support substrate.
