Abstract: An I-V measurement method is provided for a solar cell having a collecting electrode on the first surface side of a single-crystalline silicon substrate of a first conductivity type and having a transparent electrode on the outermost surface on the second surface side of the single-crystalline silicon substrate of the first conductivity-type. An electric current is supplied to the solar cell in a state in which flexible metal foil and the transparent electrode are brought into detachable contact with each other such that the flexible metal foil follows undulations of the single-crystalline silicon substrate of a first conductivity type, and the first surface is set as a light-receiving surface. It is preferable that at least on a portion that is in contact with the transparent electrode, the metal foil is formed of at least one selected from the group consisting of Sn, Ag, Ni, In, and Cu.

Abstract: In the solar cell module, a first solar cell and a second solar cell are stacked together with an electroconductive member interposed therebetween, such that a cleaved surface-side periphery on a light-receiving surface of the first solar cell overlaps a periphery on a back surface of the second solar cell. The first solar cell and the second solar cell each have: photoelectric conversion section including a crystalline silicon substrate; collecting electrode; and back electrode. At a section where the first solar cell and the second solar cell are stacked, the collecting electrode of the first solar cell and the back electrode of the second solar cell are electrically connected to each other by coming into contact with the electroconductive member. An insulating member is provided on a part of the cleaved surface-side periphery on the light-receiving surface of the first solar cell, where the collecting electrode is not provided.
