BIPV layered hollow glass curtain wall structure

Abstract

The invention relates to a building integrated photovoltaics (BIPV) layered hollow glass curtain wall structure, which comprises front glass and rear glass, wherein a front ethylene vinyl acetate (EVA) layer, a photovoltaic solar cell layer, a rear EVA layer and a tedlar/polyethylene glycol terephthalate/tedlar (TPT) layer are sequentially arranged between the front glass and the rear glass; a space interlayer is formed between the TPT layer and the rear glass; a terminal box connected with the photovoltaic solar cell layer is arranged behind the rear glass; a fixed clamping frame is arranged at the periphery between the front glass and the rear glass; and a filtering membrane is arranged in front of the front glass. When receiving sunlight, the curtain wall structure can reflect solar rays beyond the range of between 0.4 and 1.1 micrometers, so the temperature of a glass curtain wall assembly is reduced, the service life of the integral assembly is prolonged, the heat-insulating effect of the assembly is better than that of the conventional hollow glass curtain wall, the transfer of indoor and outdoor heat can be isolated effectively, energy loss is reduced, and the energy conservation of buildings is realized.

Description

technical field [0001] The invention relates to a glass curtain wall structure, in particular to a BIPV layered hollow glass curtain wall structure. Background technique [0002] The existing BIPV layered hollow glass curtain wall structure includes a front glass and a rear glass, and a front EVA layer, a photovoltaic solar cell layer, a rear EVA layer, and a TPT layer are sequentially arranged between the front glass and the rear glass. There is a space interlayer between the glasses, and a junction box connected to the photovoltaic solar cell layer is arranged behind the rear glass; there is a fixed clamping frame around the periphery between the front glass and the rear glass. When assembled on the outside of a building, the rear glass is on the side of the building. The sunlight can pass through the front glass and shine on the photovoltaic solar cell layer. Since the sunlight that can be used for power generation is 0.4-1.1μm, the other sunlight is useless. However, th...

Problems solved by technology

The sunlight can pass through the front glass and shine on the photovoltaic solar cell layer. Since the sunlight that can be used for power generation is 0.4-1.1μm, the other sunlight is useless. However, the sunlight beyond 0.4-1.1μm It will generate a certain amount of heat, which increases the temperature of the entire glass curtain wall assembly and has a certain impact on its life.
