SOLAR CELL AND SOLAR CELL MODULE USING THE SAME

摘要

Disclosed are a solar cell and a solar cell module using the same. The solar cell according to the embodiment includes a stepped portion on a support substrate; a back electrode layer having a first height difference on the support substrate and the stepped portion; a light absorbing layer having a second height difference on the back electrode layer; and a front electrode layer having a third height difference on the light absorbing layer. The solar cell module according to the embodiment includes a stepped portion on a support substrate; a first solar cell on the support substrate; and a second solar cell on the stepped portion, wherein the first solar cell is electrically connected to the second solar cell on a lateral side of the stepped portion.
