Crystalline silicon BIPV building component and manufacturing method thereof

Abstract

The invention provides a crystalline silicon building integrated photovoltaics (BIPV) building component. The side facing the sun sequentially comprises outer plate glass, at least one first transparent polyvinyl butyral (PVB) layer, a crystalline silicon power generation unit, a third PVB layer and inner plate glass from outside to inside. The outer plate glass and the inner plate glass meet the requirements of building specifications, and the resistivity of the first transparent PVB layer meets the PID attenuation requirement of the crystalline silicon BIPV building component. The invention further provides a manufacturing method of the crystalline silicon BIPV building component. The manufacturing method is used for manufacturing the crystalline silicon BIPV building component. The crystal silicon BIPV building component can be installed at more positions, so that the applicability is higher; the crystalline silicon BIPV building component can be designed into various colors, can be matched with various different building styles, and is better in attractiveness; the crystalline silicon BIPV building component is better in reliability and longer in service life; the crystalline silicon BIPV building component is high in generating capacity. The manufacturing method of the crystalline silicon BIPV building component is efficient and rapid.

Description

technical field [0001] The present invention relates to the technical field related to photovoltaic building, more precisely relates to a kind of crystalline silicon BIPV building component and its manufacturing method. Background technique [0002] In order to promote energy saving and emission reduction in buildings, existing technologies mainly focus on two aspects: on the one hand, “passive” emission reduction is carried out by improving material efficiency, promoting the use of low-carbon materials, high-efficiency heat insulation building envelopes, etc.; on the other hand, vigorously promoting roof Distributed photovoltaic power plants make full use of the roof area to reduce emissions. [0003] However, there are some disadvantages in passive buildings: First, passive buildings need to increase the thickness of the external wall insulation layer, increase the building area, and reduce the housing rate; passive buildings need to be adjusted under different climatic ...

Problems solved by technology

[0003] However, there are some disadvantages in passive buildings: First, passive buildings need to increase the thickness of the external wall insulation layer, increase the building area, and reduce the housing rate; passive buildings need to be adjusted under different climatic conditions, and also need to be adjusted for different types of buildings , poor applicability; in addition, passive buildings have limited reduction in energy consumption, lack of room for improvement, and high overall cost

[0004] Rooftop distributed photovoltaic power plants also have some disadvantages: the roof area is limited and other facilities need to be installed, resulting in a small available area for photovoltaic installation, especially for high-rise buildings, with limited energy saving and emission reduction effects; in addition, rooftop distributed photovoltaic power stations and buildings The consistency is poor, affecting the overall aesthetics
