Photovoltaic module layer composition for use as solar module in building, has intermediate layer comprising optical decoupling refractive index difference for module cover and active layer unit and reflection layer with small thickness

摘要

Composition has a photovoltaic active layer unit (3) that is arranged on a support. A module cover (1) is provided over the active layer unit. A partially transparent intermediate layer (2) is provided between the module cover and the active layer unit. The intermediate layer comprises an optical decoupling refractive index difference for the module cover and the active layer unit and a reflection layer with small thickness.
