PROBLEM TO BE SOLVED: To reduce the electric resistance between adjacent photoelectric conversion cells by improving coverage of conductive thin films in open grooves for connection even if the conductive thin films for connection are thinner than the thickness of photoelectric conversion layers.SOLUTION: In the thin-film solar cell, a plurality of thin-film solar cell elements are disposed on a transparent insulating substrate 1 while sandwiching a groove 22 for connection, and thin-film solar cell elements are mutually connected in series within the groove 22 for connection. The thin-film solar cell includes an inclination part 8 made of an insulating material on a side within the groove 22 for connection. By a conductive film 6 formed on an incline at the inclination part 8, a rear side of one of the adjacent thin-film solar cell elements is electrically and serially connected to a front side of the other thin-film solar cell element. |
