PURPOSE:To acquire a solar battery module of high effective efficiency by reflecting light projected to a connection part between a bus electrode and an interconnector to an effective part which can convert light of a solar battery to current by a reflection surface of an interconnector edge part forming a specified acute angle at a position higher than a solar battery surface. CONSTITUTION:A surface electrode 5 is composed of a grid electrode 5a and a bus electrode 5b. One end of an interconnector 7 is connected to a rear electrode 6 of one solar battery, and is bent vertically from its connection part. The interconnector 7 is extended along an edge surface of the solar battery and bent to a direction of an adjacent solar battery to form an acute angle of 45 deg. or less at a position higher than a solar battery surface to from a reflection surface 7a which reflects incident light to an effective part of a solar battery which converts solar battery light to current. Therefore, it is possible to increases an effective area and to improve effective efficiency by reflecting light injected to a connection part of the bus electrode 5b and the interconnector 7 to an effective part which converts light of solar battery to current by a reflection surface of the interconnector 7. |
