Building photovoltaic integrated hollow type amorphous silicon solar cell module and manufacturing method

Abstract

The invention provides a building photovoltaic integrated hollow amorphous silicon solar cell assembly and a manufacturing method. The solar cell assembly is a stacked structure, including front encapsulation glass (1), amorphous silicon cell layer (2), Adhesive film connecting layer (3), tempered glass (4), color crystal glass back plate (5); toughened glass (4) and color crystal glass back plate (5) are fixed by hollow aluminum strips (6) around them, and The edge of the hollow aluminum strip (6) is coated with polysulfide glue (7) for sealing, and a color crystal decorative coating (8) is provided on the inner side of the color crystal glass back plate (5). The target product of the present invention is a product that adopts prefabricated tempered transfer film decoration process to cover the back area of ​​crystalline silicon wafer and amorphous silicon battery respectively and display colorful crystal pattern decoration. This target product can also be combined with Low-E energy-saving glass, which not only has a beautifying effect, but also reduces the thermal conductivity of the component when used as a curtain wall, achieving better effects of shielding sunlight, heat insulation, and light filtering.

Description

technical field [0001] The invention relates to a structure and a manufacturing method of a novel crystalline silicon and amorphous silicon solar battery module, and belongs to the field of glass deep processing and building photovoltaic integration. Background technique [0002] When crystalline silicon and amorphous silicon solar cell modules are extended to be used in building curtain walls, doors, windows, and ceilings, there are still some problems that affect the practical development of the industry. One is that the effective battery power generation area and the daylighting area will change the spacing of silicon wafers due to different needs of users. This change will result in frequent changes and calibrations of fixtures and fixtures during mass production and high manufacturing costs; the other is that the battery components can reach outdoor sunlight Surface power generation function, partial indoor light transmission function, but the monotonous color and style...

[0002] When crystalline silicon and amorphous silicon solar cell components are applied to building curtain walls, doors, windows, and ceilings, there are still some problems that affect the practical development of the industry

One is that the effective battery power generation area and the daylighting area will change the spacing of silicon wafers due to different needs of users. This change will result in frequent changes and calibrations of fixtures and fixtures during mass production and high manufacturing costs; the other is that the battery components can reach outdoor sunlight Surface power generation function, partial indoor light transmission function, but the monotonous color and style of the back of the crystalline silicon cell and the amorphous silicon cell cannot create a visual aesthetic feeling for the indoor environment, and affect the comprehensive performance of the indoor environment; the third is that architectural photovoltaic glass is used for The temperature insulation, heat insulation, sound insulation, light filtering, safety and impact resistance of curtain walls, doors and windows and ceilings are poor, and the tensile strength is low, which needs to be further improved
