A solar cell module is provided with: a plurality of solar cell elements each having a surface; a light diffusion portion provided in an outer peripheral area of the surface; and connection members which connect the plurality of solar cell elements. The outer peripheral area has restricted areas where formation of the light diffusion portion is restricted, in a part thereof, and the restricted areas are provided in positions where the outer peripheral area and the connection members intersect. The solar cell element may have, on the surface, bus bar electrodes which extend along the connection members. The restricted areas may be provided in the vicinity of ends of the bus bar electrodes.

Solar cell module and solar cell module manufacturing method

A solar cell has multiple busbar electrodes formed at intervals and multiple finger electrodes formed between the busbar electrodes. The finger electrodes comprise multiple finger parts connected only to one busbar electrode and multiple finger parts connected to only another busbar electrode. The adjacent multiple finger parts are connected to one another, and the adjacent multiple finger parts are connected to one another.

Solar cell

In a method for manufacturing a solar cell, a photoelectric conversion element, which has a surface whose outer periphery is surrounded by a plurality of sides, and a coating having light diffusivity are prepared. The coating is applied to an outer peripheral area of the surface by screen printing in a direction from a lower side, which is one of the sides, toward an upper side, which is one of the sides and which is opposed to the lower side such that an application amount of the coating to be applied along the lower side is smaller than an application amount of the coating to be applied along the upper side.
