A module (20) includes first and second optically transparent substrates (21, 22) and a plurality of annular clusters (30). The cluster (30) has a plurality of spherical solar battery cells (32), a plurality of conductive coats (31) to which first electrodes (37) of the cells (32) are electrically connected in parallel, a plurality of conductive members (48) to which second electrodes (38) of the cells (32) are electrically connected in parallel, a plurality of bypass diodes (40) connected in parallel to the conductive coat (31) via the conductive member (48), and a plurality of conductive connecting members (50) for electrically connecting the coat (31) to the conductive member (48) of the cluster (30) adjacent in a predetermined direction. The cluster (30) is structured in an annular, snow-crystalline or linear pattern and the plurality of the clusters (30) are provided, whereby allowance in ratio selectivity of a daylighting rate and power generation efficiency can be improved and design as a window material can be improved. |
