Abstract
An electricity storing solar power generation device 10 includes: solar cells including at least two kinds of solar cells 11, 12 and 13 having mutually different spectral absorption sensitivities; and electricity storing devices 21, 22 and 23 electrically connected to the solar cells. The solar cells are configured such that an nth (n being an integer of 1 or greater) solar cell spontaneously disperses light by itself by transmitting or reflecting light so as to allow a portion of light incident on the nth solar cell other than a portion of light absorbed by the nth solar cell to fall on an n+1th solar cell having a smaller band gap. Each of the solar cells is electrically connected to one of the electricity storing devices, and electric power generated by the solar cells is stored in the electricity storing devices electrically connected to the two or more solar cells.
