<p>Provided is a back electrode-type solar cell equipped with a directionality check mark that does not mechanically damage a substrate, and also provided is a back electrode-type solar cell manufacturing method capable of forming the mark without increasing the number of process steps. The back electrode-type solar cell has, on one surface of a first conductivity-type semiconductor substrate, a first conductivity-type impurity diffusion layer, a second conductivity-type impurity diffusion layer, a first electrode connected to the first conductivity-type impurity diffusion layer, and a second electrode connected to the second conductivity-type impurity diffusion layer. The first conductivity-type impurity diffusion layer and/or the second conductivity-type impurity diffusion layer in one or more edge regions of the semiconductor substrate have a shape different from in the other edge regions.</p> |
