Masai double glass module

Double glass module: the front and back two pieces of glass + photovoltaic cells are compounded by encapsulation film. Traditional double glass module package: EVA+EVA, EVA+POE, POE+POE. Jiaxing Fuying double glass module package: PVB+PVB.

Recently several double-glass (also called glass–glass or dual-glass modules) c-Si PV modules have been launched on the market, many of them by major PV manufacturers. These modules use a sheet of tempered glass at the rear of the module instead of the conventional polymer-based backsheet. There are several reasons why this structure is appealing.

Jiaxing Fuying double glass module package: PVB+PVB. The life cycle is longer, the warranty for ordinary modules is 25 years, and the warranty for double glass modules is 35 years. The attenuation is low, the attenuation of the traditional module is about 0.7%, and the double glass module is 0.5%.

Double-glass PV modules are emerging as a technology which can deliver excellent performance and excellent durability at a competitive cost. In this paper a glass–glass module technology that uses liquid silicone encapsulation is described. The combination of the glass–glass structure and silicone is shown to lead to exceptional durability.

Double glass PV module is known as the ultimate solution for the module encapsulation technique. Although double glass modules have many advantages, they are not yet widely used in photovoltaic power plants, for which one important reason is the large power loss due to the transmission of light in the cell gap region.

In this paper a glass–glass module technology that uses liquid silicone encapsulation is described. The combination of the glass–glass structure and silicone is shown to lead to exceptional durability. The concept enables safe module operation at a system voltage of 1,500V, as well as innovative, low-cost module mounting through pad bonding.
