Solar module

Abstract

The present disclosure provides a solar module including an encapsulation layer, a plurality of solar cells embedded in the encapsulation layer with gaps between the solar cells; and a first patternedlayer formed on the encapsulation layer and corresponding to locations of the gaps so as to absorb the light penetrating through the gaps, thereby shielding buildings from sunlight and thus saving energy.

Description

technical field [0001] The invention relates to a solar cell, in particular to a solar module integrated with multiple solar cells. Background technique [0002] for building facades High-quality silicon crystal solar modules need to have high durability and safety, and the appearance pattern must be smooth, so as to meet the quality requirements required by the building. [0003] Such as Figure 1A As shown, the existing silicon crystal solar module 1 utilizes a glass cover plate 12 and a back sheet (Back Sheet) 11 to package the string-welded solar cells (Solar Cell) 13 in a transparent or partially white packaging layer 10, and then A foam tape (foam tape) 14 is used to bond the aluminum frame 15 around the package, wherein the material forming the package layer 10 can be ethylene / vinyl acetate copolymer (Ethylene Vinyl Acetate, referred to as EVA) or polyvinyl alcohol. Butyraldehyde (PVB). [0004] However, considering the durability and safety, the aforementioned so...

Problems solved by technology

[0006] However, in the aforementioned solar module 1', the light will penetrate the gap w between the solar cells 13 and irradiate the building through the glass plate 11', so that whether the transparent or partially white encapsulation layer 10 is used, the appearance All will present the lattice pattern of the solar cells 13, thereby beautifying the building and making it unable to meet the aesthetic requirements, and the encapsulation layer 10 is easily exposed to ultraviolet light and turns yellow, which makes the building appear old at an accelerated rate.

[0007] Furthermore, the size of the existing solar module 1' used on the facade needs to match the building specifications, such as 600㎜x 1200㎜ or 900㎜x 1800㎜, which is not the standard size of the traditional silicon solar module (such as 60 solar cells The size of 1656㎜x992㎜ or the size of 1956㎜x992㎜ for 72 solar cells), so when the transparent or partially white encapsulation layer 10 is used, the sunlight can directly penetrate a very large area on the solar module 1' ( Through the gap w) between the solar cells 13, it irradiates to the outer wall of the building, so that the solar module 1' cannot achieve the effect of shielding the outer wall of the building, and the temperature of the outer wall of the building is extremely high during sunshine, so it needs to Increase the power consumption of air conditioners (or air conditioners) during temperature adjustment, resulting in a very high proportion (about 24% or more) of energy consumption of buildings (such as power consumption of air conditioners) in the overall energy consumption, making it difficult to meet the needs of energy conservation
