PURPOSE: A double-layered glass equipped with photovoltaic module is provided to increase light availability ratio and preventing decrease of photovoltaic efficiency by using bifacial photovoltaic module. CONSTITUTION: A double-layered glass equipped with photovoltaic module comprises plate glass(20), photovoltaic module(10) which converts light into electricity, heat-insulating layer(40) which isolates the plate glass from the photovoltaic module, and reflecting part(50) which transfers light passed through the plate glass to the photovoltaic module inside the insulation layer. The plate glass consists of outer side of double-layered glass building, and the photovoltaic module is located more inner side of the building than the glass plate. The reflecting part is located at least one of the following locations: upper end, lower end, and both end sides of the insulation layer. Concavo-convexes are formed on reflected surfaces of the reflecting part. The photovoltaic module is double-faced photovoltaic module. The plate glass is a pyrex glass. |
