The present invention is a solar cell which is provided, on a back surface of a semiconductor substrate of a first conductivity type, said semiconductor substrate having a region of the first conductivity type and a region of a second conductivity type on the back surface that is on the reverse side of a light-receiving surface, with a first finger electrode that is composed of a first contact part and a first collector part, a second finger electrode that is composed of a second contact part and a second collector part, a first bus bar electrode and a second bus bar electrode. This solar cell is provided with an insulating film at least in the entire region directly below the first bus bar electrode and the second bus bar electrode, and the first collector part and the first bus bar electrode as well as the second collector part and the second bus bar electrode are electrically connected with each other on the insulating film. The first contact part and the second contact part are continuous in a line at least directly below the insulating film. Consequently, the present invention provides a solar cell having a wide passivation region, low wiring resistance, high parallel resistance and high conversion efficiency, and also provides a solar cell manufacturing method which enables the production of such a solar cell at low cost. |
