摘要：
A thin film solar cell includes, on a substrate, a first electrode layer formed of a transparent conductive material, a photoelectric conversion layer, and a second electrode layer including a conductive material that reflects light. The thin film solar cell includes a plurality of unit solar battery cells divided by scribe lines. The second electrode layer and the first electrode layer of the unit solar battery cell adjacent to the second electrode layer are connected in the scribe line formed in the photoelectric conversion layer. The unit solar battery cells are electrically connected in series. The scribe lines on both sides of at least one of the unit solar battery cells are formed such that the unit solar battery cell held between the scribe lines meanders while having fixed width in a predetermined direction and have same shapes that overlap when the scribe lines translate in the predetermined direction.
