Abstract: Provided is a solar cell module in which a stress of a solar cell string is relieved. A solar cell module includes a plurality of solar cell elements, each including a light receiving surface and a back surface positioned on a back side of the light receiving surface, and a plurality of conductor wires, each connecting one of the solar cell elements to any of the solar cell elements which is adjacent thereto and including connecting portions to be connected to one surface of one of the solar cell elements, wherein the plurality of solar cell elements is protruded toward the light receiving surface side in a perpendicular section to a longitudinal direction of the connecting portions.

Abstract: Disclosed is a solar cell module wherein the stresses exerted on a solar cell module are relaxed. Specifically, disclosed is a solar cell module which comprises: a plurality of solar cell elements each including a light receiving surface and a rear surface positioned on a reverse side oppositely away from the light receiving surface; and leads connecting one of the solar cell elements and another adjacent solar cell element and including a connection portion connected to one surface of the one solar cell element. At least one of the solar cell elements has a wavy shape in a lengthwise direction of the connection portion.

Abstract: A solar cell module includes a substrate including a first surface receiving a light and a second surface disposed at a back side of the first surface, a first electrode provided on the first surface of the substrate, and a second electrode provided on the second surface of the substrate and including a first opening immediately below the first electrode, wherein a part of the periphery of the first electrode is disposed in the first opening as seen in a perspective plain view.

Abstract: On a substrate made of a single crystal of La.sub.3 Ga.sub.5.5 Nb.sub.0.5 O.sub.14, an excitation electrode 2 for generating a surface acoustic wave is provided to produce a surface acoustic wave device S. The cutting angles of the substrate and the direction of propagation of the surface acoustic wave are defined in Eulerian angle indication (.phi., .theta., .psi.) by .phi.=50.degree.+60.degree..times.m1, .theta.=125.degree.+180.degree..times.m2 and .psi.=40.degree.+180.degree..times.m3 (where m1, m2 and m3 are integers). Eulerian angles may be .phi.=10.degree.+60.degree..times.n1, .theta.=125.degree.+180.degree..times.n2, and .psi.=70.degree.+180.degree..times.n3 (where n1, n2 and n3 are integers) or .phi.=a1+60.degree..times.b1, .theta.=a2+180.degree..times.b2 and .psi.=a3+180.degree..times.b3 (where 0.degree..ltoreq.a1.ltoreq.60.degree., 125.degree..ltoreq.a2.ltoreq.165.de gree., 110.degree..ltoreq.a3.ltoreq.165.degree., and b1, b2 and b3 are integers).
