    摘要: 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.

    摘要: A solar cell includes: first conductivity-type layers and second conductivity-type layers each provided on a rear surface of a semiconductor substrate; first electrodes provided on the first conductivity-type layers; and second electrodes provided on the second conductivity-type layers. The first electrodes and the second electrodes are spaced apart from each other, and the first electrodes include a plurality of regions isolated from one another by the second electrodes disposed therebetween. Each of the plurality of regions of the first electrodes includes a non-mounting electrode section and a wiring-mounting electrode section having a larger electrode height than the non-connection electrode section. In two adjacent first electrode regions, an imaginary line connecting the top of the wiring-mounting electrode section of one of the regions and the top of the wiring-mounting electrode section of the other region does not cross the second electrode disposed between the two regions.

    摘要: The solar cell includes an n-type semiconductor layer and a p-type semiconductor layer on a first principal surface of a crystalline silicon substrate. The n-type semiconductor layer is provided so as to extend over a part on a p-type semiconductor layer-formed region provided with the p-type semiconductor layer, and a p-type semiconductor layer non-formed-region where the p-type semiconductor layer is not provided. In a region where the n-type semiconductor layer is provided on the p-type semiconductor layer, a protecting layer is between the p-type semiconductor layer and the n-type semiconductor layer. The protecting layer includes: an underlying protecting layer that is in contact with the p-type semiconductor layer; and an insulating layer that is on the underlying protecting layer. The underlying protecting layer includes an intrinsic silicon-based layer or an n-type silicon-based layer.
