Solar cell module

A solar cell module comprising:

• two base plates each including a conductive layer on at least one side;
• and
• a plurality of submodules interposed between respective conductive layers of the two base plates, wherein
• the plurality of submodules each include a plurality of cells connected to each other as a result of a conductive material electrically connecting the respective conductive layers of the two base plates,
• the plurality of cells are arranged in a first direction,
• the plurality of submodules are arranged in a second direction orthogonal to the first direction,
• the two base plates each have a plurality of insulating grooves, each defining a recess, extending in the first direction in a gap between the plurality of submodules,
• the plurality of insulating grooves of one of the two base plates and the plurality of insulating grooves of an other one of the two base plates define at least one insulating space extending in the first direction that prevents short circuiting between adjacent submodules,
• the conductive material has a spherical shape and a maximum dimension of 0.5 μm or more and 30 μm or less, and
• the at least one insulating space is capable of containing the conductive material that is not in contact with at least one of the conductive layers so as to create a state in which the conductive material is not in contact with at least one of the conductive layers.
