Abstract: A solar cell module includes a solar cell string in which a first solar cell and a second solar cell are arranged apart from each other along a first direction. The first and second solar cells are connected by a strip-shaped wiring member, and the solar cell string is arranged between a light-receiving-surface protection member and a back-surface protection member. The wiring member has, along the first direction, an uneven region where the first principal surface is provided with unevenness, and a flat region where the first principal surface is not provided with unevenness or is provided with unevenness that is smaller in height than the uneven region. The uneven region extends from the light-receiving surface of the second solar cell to the back surface of the first solar cell.

Abstract: A sample-holding device for holding and lifting a sample includes a sample-holding surface facing the sample; and a positioning member provided at a peripheral part of the sample-holding surface, the positioning member comprising a contact part having an outward-facing part on a back side thereof; a first rounded or chamfered end; and a second rounded or chamfered end, wherein the contact part contacts with part of the sample when the sample is held or when the sample is off-point, wherein the first end is an end of a section comprising the contact part or a part smoothly continuing from the contact part, the end being on a distant side from the sample-holding surface, and the second end is an end of the outward-facing part, the end being located on a tipping side of the outward-facing part.

Abstract: The method for manufacturing a crystalline silicon substrate for a solar cell includes: forming a texture on the surface of a single-crystalline silicon substrate by bringing an alkali solution and the surface of the single-crystalline silicon substrate into contact with each other; bringing an acidic solution and the surface of the single-crystalline silicon substrate into contact with each other to perform an acid treatment thereon; and then by bringing ozone water and the surface of the single-crystalline silicon substrate into contact with each other to perform an ozone treatment thereon. One aspect of embodiment is that the acidic solution used for the acid treatment is hydrochloric acid. Another aspect of embodiment is that the ozone treatment is performed by immersing the single-crystalline silicon substrate into the ozone water bath.
