PURPOSE:To simplify a connecting method by a mechanism wherein when a plurality of solar battery consisting of semiconductor thin films are formed on an insulator substrate, a P type layer formed on a concave and an N type layer formed on a convex surface are directly touched with each other, using an uneven and stepped substrate as a base. CONSTITUTION:A substrate made concavo-convex steps is used as an insultor substrate 301, and on the first concave, a P type amorphous semiconductor 303a, an intrinsic amorphous semiconductor 302a and an N type amorphous semiconductor 304a are laminatingly formed to construct one solar battery. Then, on the convex adjacent to the concave, is provided one solar battery composed of a P type amorphous semiconductor 303b, an intrinsic amorphous semiconductor 302b and N type amorphous semiconductor 304b, and an end of the highest layer 304a of the concave and an end of the lowest layer 303b of the convex are brought in contact, by using the concavo-convex steps. In such a manner, individual solar batteries are connected in series and the solar batteries formed on the same plane of the convex are insulated by means of an insulating film 306 and at the same time, connected through a conductive layer 305 attached to the insulating film 306. |
