Abstract
A solar cell includes a tunneling layer located on one side of a semiconductor substrate, a first conductive region located on the tunneling layer, a first insulating film located on and passivating the first conductive region, a second conductive region located at the other side of the semiconductor substrate and composed of a doping region, a first electrode connected to the first conductive region, and a second electrode connected to the second conductive region. The first conductive region includes a first part connected to the first electrode and a second part other than the first part, and a thickness of the first part is different from that of the second part.
