See-through type solar battery module (20) includes optically transparent first and second substrates (21, 22) and a plurality of annular clusters (30), with each cluster (30) including: a plurality of spherical solar cells (32); a conductive layer (31) to which first electrodes (37) of the plurality of solar cells (32) are electrically connected in parallel; a conductive member (48) to which second electrodes (38) of the plurality of solar cells(32) are electrically connected in parallel; a bypass diode (40) connected to the conductive layer (31) and the conductive member (48); and a conductive connection member (50) that electrically connects the conductive layer (31) to conductive member (48) of the cluster (30) that is adjacent in a predetermined direction. By providing the plurality of clusters (30) arranged in an annular configuration, in a snowflake configuration, or in a single rectilinear pattern, it is possible to enlarge the permitted scope for selection of the ratio between sunlight transmission ratio and electrical generation capability, so that it is possible to obtain enhanced freedom of design for use as a window material. |
