Length, H1 is the most deep degree of sunk structure 11, and W1 is the width of sunk structure, and L1 is the length of sunk structure.This implementation
The most deep degree H1 and thickness of glass H of sunk structure 11 ratio is 1 in example：100-1:2, further, sunk structure 11
Most deep degree H1 is 0.03-10 ㎜, and the width W1 of sunk structure 11 is 0.3-50 ㎜, and the length L1 and glass of sunk structure 11 are long
The relation for spending L is L-60 ㎜≤L1≤L-10 ㎜.
The depth of the utility model sunk structure is millimetre-sized, and anti-reflection effect is stable in natural environment, and self-cleaning is more preferable,
Surface easy cleaning.The depth for being different from sunk structure be it is nano level, nano level cup depth be substantially very little from
Sub- etch pit, tiny etch pit less, is easily gradually corroded to the anti-reflection contribution of light in the environment for the dust storm that exposes to the sun and rain
Polish, and then reduce anti-reflection effect；The impurity such as the dirt accumulated in the groove of nanostructured do not allow easy-clear, further influence light
Utilization rate.
As shown in Fig. 9-Figure 12, it is preferable that sunk structure 11 is the sunk structure extended along glass length direction, sunk structure
11 battery chip arrays 3 smooth surface orthographic projection in the plane it is substantially rectangular；Wherein, multiple raised knots on on-plane surface
Structure increases the light-receiving area of glass, adds the utilization rate of light；Light being capable of multiple reflections refraction, light profit by sunk structure
Improved with rate.

The edge of the backboard 5 of 2/ battery chip arrays of film layer, 3/ gum film layer 4/ is to seal solar cell module, positioned at installation housing 6
The side away from battery chip arrays of interior glass 1 is plane, installs housing 6 and the battery chip arrays 3/ of foreboard/front adhesive film layer 2/
The connection of the edge of the backboard 5 of gum film layer 4/ is prior art, be will not be repeated here.Further, glass 1 in foreboard
Away from the side of battery chip arrays provided with correspondence install housing set encapsulation side 12, apart from four edges of glass 1 away from
It is 5-30 ㎜ from D2.
As shown in figure 14, in the utility model in foreboard glass 1 the side towards battery chip arrays 3, i.e., in face of battery
The smooth surface of chip arrays 3 can be smooth surface or matte（Such as frosted glass）, matte generally refers to the surface with certain roughness,
For example can be, with micron or nano level concaveconvex structure, to visually observe, have no obvious concave or convex, it is only in accuracy
For irregular concaveconvex structure can be shown under micron or nano level optical viewer, specifically, recessed and/or male structure most deep
Spend the most deep degree H1 well below herein described sunk structure.Opposite side, i.e. the glass away from the side of battery chip arrays 3
Glass 1 is towards the sun.Further, the material of backboard 5 can be identical or different with the material of foreboard.
