PROBLEM TO BE SOLVED: To provide a light-transmitting solar battery module that allows observation of outdoor scenery from indoors even at night when external light is extremely weak.SOLUTION: A sun light-transmitting type solar battery module 10 is composed of: a unit battery cell 2 including a transparent surface electrode layer 4, a photo-electric conversion layer 5, a back face metal electrode layer 6 and a back face protective layer 8, successively layered on a transparent insulating substrate 1; and a light-collecting part 3 comprising a separation region formed by arranging a plurality of the unit battery cells 2 separated from one another. An antireflection layer 7 is formed on a surface on a back face protective layer 8 side of the back face metal electrode layer 6. |
