It has the advantages of beautiful, transparent and controllable, energy-saving and power generation, and it does not need fuel, no waste gas, no waste heat, no waste residue, no noise pollution. It is widely used. Our photovoltaic glass window is composed of five layers of glass-PVB (EVA) film – solar cell -PVB(EVA) film – glass, similar to the commonly used laminated glass in construction. It has good security. Photovoltaic glass window with light transmittance of 5%~80% can be made by controlling the cell gap and edge gap between the double-sided glass. There are also hollow photovoltaic glass is to replace the outer glass of hollow glass with double glass laminated photovoltaic module, in the production process than double glass laminated photovoltaic module more synthetic hollow steps.
