<p>PROBLEM TO BE SOLVED: To provide a solar battery cell for light convergence power generation, where deterioration of power generating efficiency which is generated by irregularities in irradiation on a light-receiving surface is reduced, when a load is connected. SOLUTION: In a solar battery cell 16, a recombination reducing means is installed, where the pitch of a thin-line part of a comb-shaped upper electrode 22 arranged on a central region A of alight receiving surface 14 is made greater than almost three times that in the other region, and the density of an arranged number is reduced to almost one third. Since a recombination current in the central region A is reduced, consumption of current generated in the other region becomes low, and the power generating efficiency with a load connected can be improved.</p> |
