Problems solved by technology

[0039] As mentioned above, in conventional solar cells (cells, modules), if the yield from a circular shape is improved when forming solar cells, the solar energy in a solar cell module formed by arranging a plurality of solar cells will The filling rate of the battery cell is lowered. In addition, if the filling rate of the solar battery unit is increased, the yield of the solar battery unit is lowered, etc., and a high yield and a high filling rate cannot be fully achieved.
