Abstract
A method of manufacturing a thin-film solar cell includes forming a first electrode on a substrate; forming a first petition groove for dividing the first electrode; forming a semiconductor layer on the first electrode and in the first partition groove; forming a second partition groove for dividing the semiconductor layer; forming a second electrode on the semiconductor layer and in the second partition groove; and forming a third partition groove for dividing the second electrode and the semiconductor layer. At least one of the steps of forming the first partition groove, the second partition groove, and the third partition groove includes forming an opening in a partition groove forming layer to expose a lower layer surface below the partition groove forming layer, bringing a needle into contact with the lower layer surface, and forming the partition groove by moving the needle in a predetermined direction.
