Encapsulating material 2 reaches back plate 4, and most light can not all return to the front light-receiving surface of cell piece 3, only because diffusing reflection
Effect, have the front light-receiving surface that least a portion of light returns to cell piece 3 after reflection and refraction, but can reflect
The light quantity for returning cell piece 3 is relatively fewer, and since light round is long, causes the decaying of light larger, 3 energy of final cell piece
The energy enough obtained is also low；2）As China Patent No. 201621026600.6, patent name are " a kind of glass photovoltaic module "
Described in patent of invention, by pasting reflective membrane between corresponding to battery strings in photovoltaic glass lower surface, reflective membrane table will be incident to
The light in face carries out reaching the adjacent battery strings surface of reflective membrane after secondary reflection, battery strings by the light absorption after secondary reflection,
The secondary reflection that light is carried out by using the light-receiving area, increases the light income of photovoltaic module, defeated to reach raising component
Go out power, but if the photovoltaic glass in this technical solution is pattern glass, causing may in stacking and lamination process
The displacement that reflective membrane occurs, to influence photovoltaic module quality and final reflection light effect, and due to will be in battery
The reflective membrane that narrower in width is placed in the interval of piece, will greatly reduce production efficiency and yields.

It is reflected to the front of cell piece 3.
Light-reflecting portion 5 in the above implementation column and the other embodiment that can be obtained according to the technique and scheme of the present invention is in light
The setting lied prostrate on glass 1 has various ways, as shown in figures 13-18（In following several ways, four side blank of photovoltaic module
Region is correspondingly arranged on light-reflecting portion 5）：
1）The gap of the correspondence adjacent cell of light-reflecting portion 5 piece 3 is laterally consecutive or interruption is arranged, if Figure 13 expressions are that light-reflecting portion 5 is right
Answer the laterally consecutive setting in the gap of adjacent cell piece 3；
2）The gap that light-reflecting portion 5 corresponds to adjacent cell piece 3 is longitudinally continuous or is interrupted setting, if Figure 14 expressions are that light-reflecting portion 5 is right
The gap of adjacent cell piece 3 is answered to be longitudinally continuous setting；
3）The gap of the correspondence adjacent cell of light-reflecting portion 5 piece 3 is horizontal and vertical to be continuously or discontinuously arranged, if Figure 15 expressions are reflective
Portion 5 corresponds to the horizontal and vertical interruption setting in gap of adjacent cell piece 3, and Figure 16 expressions are that light-reflecting portion 5 corresponds to adjacent cell piece 3
Gap is crisscross and laterally intermittent setting；Figure 17-18 expressions are the gap transverse direction that light-reflecting portion 5 corresponds to adjacent cell piece 3
It is arranged with being longitudinally continuous.
But in specific practice, needs to be selected according to practical situation, such as need the area of light-reflecting portion 5 most
Greatly, reflecting effect is optimal, then preferred light-reflecting portion 5 corresponds to the horizontal and vertical continuous setting in gap of adjacent cell piece 3；As needed to reach
To certain reflecting effect and control cost, then the gap of the correspondence adjacent cell of preferred light-reflecting portion 5 piece 3, which is laterally or longitudinally interrupted, sets
It sets.
In light-reflecting portion 5 in the above implementation column and the other embodiment that can be obtained according to the technique and scheme of the present invention all
The setting of reflective structure 51 can be carried out according to actual demand, reflective structure 51 includes but not limited to following situations：Special-shaped is micro-
Hole（As shown in figure 19）, saw-tooth-type structures, cabochon micro-structure, pyramid structure, micro- prism of corner cube structure（Such as Figure 20 institutes
Show）, ball-shaped structure（As shown in figure 21）.
At least one of back plate 4 and foreboard are the photovoltaic glass with light-reflecting portion 5 in the above implementation column.Light-reflecting portion 5 is equal
Reflecting strips or reflecting thread are may be configured as, the width of light-reflecting portion 5 is configured according to actual service condition.And in order to preferably
The reflecting effect for realizing light-reflecting portion 5 can be in light-reflecting portion 5 in the case where not influencing light-reflecting portion 5 and being combined with photovoltaic glass 1
Upper setting reflective structure 51 and/or reflective layer, reflective layer, which uses, is covered with the means such as reflecting coating preferably to reflect incident light.
A kind of photovoltaic glass of the present invention is integrated light-reflecting portion and photovoltaic glass by the way that light-reflecting portion is arranged in photovoltaic glass
Integrally, avoid the later stage cell piece gap place reflecting strips various troublesome operations；Reflecting surface photovoltaic glass has been increased to
In glass, it is higher than the surface of cell piece, so that reflective height increases, the Distance Shortened of light reflection can will be more
Light be reflected back cell piece front, improve the generating efficiency of photovoltaic module.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention, all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
