Title: Stacked solar cell device

Abstract: This stacked solar battery device includes a plurality of solar battery units 4, an enclosure case made of a metal plate to house these solar battery units 4 therein, a cover glass having a partial cylindrical lens formed. The plurality of solar battery units 4 are housed in a plurality of recesses of the enclosure case, and are sealed with a sealing material of synthetic resin. The solar battery unit 4 has a planar light receiving solar battery module 10, and rod light receiving solar battery modules 30 and 50 stacked so that the module having a shorter center wavelength of the sensitivity wavelength band is positioned closer to the incident side of the sunlight. The solar battery module 10 is configured so that five planar light receiving solar-battery cells 11 are connected in parallel with four connection rods 20a and 20b, and the sunlight modules 30 and 50 are configured so that five sub modules 31 and 51 are connected in parallel respectively with the connection rods 40a, 40b, 60a and 60b. The sub modules 31 and 51 are configured so that a plurality of rod-shaped solar battery cells 32 and 52 respectively are connected in series.
