Abstract
A thin film solar cell module includes a substrate, at least one first cell positioned in a central area of the substrate, and at least one second cell positioned in an edge area of the substrate. Each of the first and second cells includes a first electrode, a second electrode, and at least one photoelectric conversion unit positioned between the first electrode and the second electrode. An amount of germanium contained in the photoelectric conversion unit of the first cell is less than an amount of germanium contained in the photoelectric conversion unit of the second cell positioned on the same level layer as the photoelectric conversion unit of the first cell.
