Solar cell structural body, solar cell array and sunlight power generation system

摘要

A solar cell structural body having a solar cell arranged on a concrete retaining body comprising a concrete prepared from a mixture comprising at least a cement, water and an aggregate, such that part of a conductor portion of said solar cell is contacted with said concrete retaining body, characterized in that said concrete has a resistivity in a range of from 9x103 to 120x103 OMEGA.cm. A solar cell array in which said solar cell structural body is used, and a sunlight power generation system in which said solar cell structural body is used.
