摘要： A solar cell module comprises cell groups each containing solar cells, and each solar cell includes photoelectric converters, N number of which being connected in series, and first, second and third terminals. When the first terminal on one end of a first cell group has a reference potential, the second terminal on the other end of the mth cell group is connected to the first terminal on one end of another cell group, and N number of the third terminals of the mth cell group are respectively connected to N number of the first terminals of an m+1th cell group. The difference in potential between the second terminal on the other end of the mth cell group and the first terminal on one end of the other cell group is 10% or less of the difference in potential between the second and first terminals of the mth cell group.

摘要： Provided is a solar cell including a photoelectric conversion section having a first principal surface and a second principal surface, and a collecting electrode formed on the first principal surface of photoelectric conversion section. The photoelectric conversion section includes a semiconductor-stacked portion including a semiconductor junction, a first electrode layer which is a transparent electrode layer formed on the first principal surface side of the semiconductor-stacked portion, and a second electrode layer formed on the second principal surface side of the semiconductor-stacked portion. The collecting electrode includes a first electroconductive layer and a second electroconductive layer. In the manufacturing method, an insulating layer is formed on the first electrode layer, and the electrode layer exposed to the surface of the insulating layer-non-formed region is removed to eliminate a short circuit between the first and second electrode layers. The second electroconductive layer is formed by plating.

摘要： A method for manufacturing a crystalline silicon-based solar cell having a photoelectric conversion section includes a silicon-based layer of an opposite conductivity-type on a first principal surface side of a crystalline silicon substrate of a first conductivity-type, and a collecting electrode formed by an electroplating method on a first principal surface of the photoelectric conversion section. By applying laser light from a first or second principal surface side of the photoelectric conversion section, an insulation-processed region his formed where a short-circuit between the first principal surface and a second principal surface of the photoelectric conversion section is eliminated. On the collecting electrode and/or the insulation-processed region, a protecting layer s formed for preventing diffusion of a metal, which is contained in the collecting electrode into the substrate. After the protecting layer is formed, the insulation-processed region is heated to eliminate leakage between the substrate and the silicon-based layer.
