Color photovoltaic module for building interior decoration and preparation method thereof

Abstract

The invention discloses a color photovoltaic module for building interior decoration and a preparation method thereof. The color photovoltaic module comprises frontal glass, a frontal sealing layer, a double-sided solar cell array, a rear sealing layer and rear glass from top to bottom in sequence, wherein the double-sided solar cell array is provided with a plurality of double-sided solar cells; the rear surface of each double-sided solar cell has a single color; the rear surfaces of the double-sided solar cells have at least one color. According to the color photovoltaic module and the preparation method thereof, a multi-color pattern can be acquired, building beauty is increased for internal visitors to appreciate, double-sided power generation can be realized, good transmission of light is achieved, and the power generation efficiency of the color photovoltaic module is improved.

Description

technical field [0001] The invention relates to a colored photovoltaic module for building interior decoration and a preparation method thereof, belonging to the technical field of photovoltaic modules, and can be used for building photovoltaic curtain walls, exhibition hall roofs, vegetable greenhouses, overpass corridors, parking lot ceilings and the like. Background technique [0002] At present, photovoltaic modules on the market are mainly monocrystalline silicon solar cell components and polycrystalline silicon solar cell components. Its component structure is generally glass-encapsulation material-battery-encapsulation material-backplane / glass. The back side of the battery is prepared by screen-printing Al paste, and the Al paste appears gray after sintering; while on the front side of the battery, in order to maximize sunlight absorption, it is generally required that the front silicon nitride anti-reflection coating be blue. After the module is encapsulated, the fr...

Problems solved by technology

This conventional component has a single color and is applied to building integrated photovoltaics. It cannot be well coordinated with the building color and cannot increase the external beauty of the building.

[0003] For conventional components, the back is covered by the back plate, which is uniform off-white and monotonous in color. For the interior of the building, it is difficult to achieve the effect of building interior decoration; panels to form a double-sided light-transmitting double-glass module. The advantage of this module is that it has good light transmission performance, and the indoor brightness can be adjusted by adjusting the area covered by the battery sheet.

But this kind of double-glass module has poor aesthetics on the back, because the back of the solar cell used is dark gray, which affects the visual effect
