Double side photovoltaic battery wall component and manufacturing process thereof

Abstract

The invention belongs to the field of photoelectricity and building materials and particularly relates to a double-side photovoltaic battery curtain wall assembly and the fabrication method thereof. The double-side photovoltaic battery curtain wall assembly comprises an upper glass layer, a bottom glass layer, and solar battery slices, wherein the upper glass layer, the bottom glass layer and the solar battery slices are hermetically bonded with each other through EVA; the solar battery slice is a double-side monocrystalline silicon solar battery slice; double-side monocrystalline silicon solar battery slices are connected with each other through interconnection strips; and each solar battery slice groups is connected with a terminal box through a bus bar. The fabrication method of the double-side photovoltaic battery curtain wall assembly is also provided. The invention can solve the purpose problem of double-side battery, so that the double-side batteries can be used in the photoelectrical field more generally. The double-side solar battery, i.e. the positive and the negative side of the battery slice, can generate corresponding power under the irradiation of solar light, so that the power of the photovoltaic assembly is increased indirectly, the conversion efficiency of the single battery slice is improved.

Description

technical field [0001] The invention belongs to the fields of optoelectronics and building materials, and in particular relates to a double-sided photovoltaic cell curtain wall assembly and a manufacturing method thereof. Background technique [0002] Curtain wall components, that is, use special resin to paste solar cells on the glass, inlaid between two pieces of glass, and convert light energy into electrical energy through the cells. In addition to the main function of power generation, the photovoltaic curtain wall also has obvious functions such as heat insulation, sound insulation, safety, decoration, etc. In particular, solar cell power generation will not emit carbon dioxide or produce harmful gases to the greenhouse effect, and has no noise. Net energy, good compatibility with the environment. Curtain wall components are a new type of building material that integrates power generation, sound insulation, heat insulation, safety, and decoration functions, fully embo...

Problems solved by technology

[0003] The patent number is: 03254467.7, and the patent name is: The Chinese patent of photoelectric glass curtain wall assembly discloses a glass curtain wall assembly made of monocrystalline silicon and polycrystalline silicon solar cells using block cells. There is no filler in the light-transmitting gap left between the cells, so the cells are easy to shift, the interconnection bars and bus bars are twisted, and there are air bubbles in the photoelectric interlayer, which greatly affects the photoelectric performance of the battery, and the appearance is also very unsightly.

[0004] At present, traditional curtain wall components use single-sided monocrystalline solar cells or polycrystalline solar cells in the selection of solar cells. The disadvantage of single-sided solar cells is that only one side can be used to collect sunlight and convert light energy Converted into electrical energy; but because the back is made of glass as the back plate, the glass is light-transmitting, and this single-sided battery can only use one side to generate electricity, which is undoubtedly a waste of choice for the back plate material
