Abstract: A solar cell module includes: a light-diffusing member adjacent to a solar cell; a tab line disposed on front surfaces of solar cells and having a light-diffusing shape on a light-entering side; and a protective member having first and second principal surfaces. When an average distance between a front surface of the solar cell and the second principal surface is expressed as D, a refractive index of the protective member is expressed as n, and a critical angle for total reflection satisfying sin R=1/n is expressed as R, the tab line is disposed in a zone other than a zone between a position at a distance of 3.46×D from, among ends of the light-diffusing member, an end closest to the solar cell and a position at a distance of 2×D×tan R from, among the ends, an end farthest from the solar cell.

Abstract: A plurality of finger electrodes are disposed on a surface of a photoelectric conversion layer 60 and extend in a first direction. The plurality of finger electrodes are arranged in a second direction in which an inter-cell wiring member adapted to be disposed on the surface of the photoelectric conversion layer extends. A height of each of those of the plurality of finger electrodes disposed toward ends in the second direction from a part of the photoelectric conversion layer where the inter-cell wiring member is adapted to be disposed is larger than a height of the finger electrode disposed at a center in the second direction from the part of the photoelectric conversion layer where the inter-cell wiring member is adapted to be disposed.

Abstract: A method for manufacturing a solar cell includes: providing an electrode layer containing thermosetting resin on at least one of a first main surface and a second main surface, located opposite to the first main surface, of a photoelectric conversion unit; heating the electrode layer by irradiation of infrared light; and producing an air stream around the photoelectric conversion unit during irradiation of infrared light. The irradiation of infrared light may include irradiation of first infrared light from a first emitter facing the first main surface; and irradiation of second infrared light from a second emitter facing the second main surface.

Abstract: A first finger electrode group including finger electrodes on the first principal surface. A second finger electrode group including finger electrodes on the second principal surface. The second finger electrode group is divided into divided electrode portions, the number of electrodes of the electrode portions decreasing as a distance from a central portion of the second finger electrode group increases towards outside, and a coupling portion is arranged between each adjacent ones of the divided electrode portions and electrically connects at least two of the finger electrodes of the divided electrode portion on inside with at least one of the finger electrodes of the divided electrode portion on outside. The number of finger electrodes of the divided electrode portion closest to the central portion of the second finger electrode group is larger than the number of finger electrodes of the first finger electrode group.
