Claim:
1. An electricity storing solar power generation device, comprising: a plurality of solar cells, the plurality of solar cells including two or more solar cells that have mutually different spectral absorption sensitivities, that are arranged in an order of decreasing band gap in terms of a light path direction of incident light, and that each disperse the incident light by transmitting or reflecting a portion of the incident light that is not absorbed by the solar cell, thereby allowing the portion of the incident light to fall on a next solar cell disposed at a downstream side with respect to the light path direction; and two or more electricity storing devices, each of the two or more solar cells being directly or indirectly electrically connected to one of the two or more electricity storing devices, and electric power generated by each of the two or more solar cells being stored in the electricity storing device electrically connected to the solar cell.
