Abstract
The utility model discloses a surface structure of a solar cell sheet. The cell sheet is clamped among packaging material, a concavo-convex structure is compacted on the upper surface of the cell sheet, a waveform upper surface is formed on the cell sheet, and the upper surface of the cell sheet is an accidented surface with convex or concave points. According to the surface structure of the solar cell sheet, the concavo-convex structure is compacted on the upper surface of the cell sheet, thereby the light receiving area of the cell sheet is effectively increased, the absorptivity of the solar cell sheet for incident light is increased through the diffuse reflection for light by the concavo-convex structure on the surface of the cell sheet, linear reflection is effectively avoided, and thereby thephototransformation efficiency is effectively raised.
Description
Technical field
The utility model relates to battery, relates to a kind of solar battery sheet surface texture in particular.
Background technology
Solar energy more and more is subjected to extensive use as a kind of cleaning, the free of contamination energy, as is applied in solar LED street lamp with energy-conservation and landscape effect etc.In addition, also have the flexible solar plate, utilize solar energy to be converted into electric energy through silicon chip too, it is simple in structure, can be bent to curved surface shape or any irregularly shaped arbitrarily, is convenient for carrying and uses.For in flexible solar panel, be plate solar panel to sunlight towards bigger with irradiating angle sensitiveness, the photonasty of solar battery sheet is good inadequately, thereby just cause battery surface relatively poor to the absorptivity of incident ray, electricity conversion is lower, if the setting angle error of solar panel will cause more light loss.
The utility model content
The purpose of this utility model is to provide a kind of surface texture of solar battery sheet, and it can make solar battery sheet have higher phototranstormation efficiency.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of solar battery sheet surface texture, this battery sheet is folded between the encapsulating material, suppresses concavo-convex structure at battery sheet upper surface.
Described battery sheet forms corrugated upper surface.
The upper surface of described battery sheet is set to have the male and fomale(M﹠F) of salient point or concave point.
Described battery sheet adopts polycrystal silicon film battery or amorphous silicon membrane battery.
After adopting said structure, with respect to original plate shaped battery sheet surface, the utility model forms concavo-convex structure with the upper surface compacting of battery sheet, thereby can effectively increase the light-receiving area of battery sheet, the concave-convex surface shape can strengthen solar cell to the absorptivity of incident ray to the diffuse reflection of light, effectively avoid line reflection, thereby can effectively improve phototranstormation efficiency.And after having suppressed sags and crests, because light angle increases, solar panels can be installed with wideer angular range, have avoided causing the reflection of light loss because of the setting angle error.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
In the flexible solar panel structure, solar battery sheet 1 generally is to be folded between the encapsulating material, and wherein, the battery sheet can adopt the polycrystal silicon film battery, or the amorphous silicon membrane battery etc.
The top of battery sheet 1 is the light accepting part branch, in the utility model, for improving the phototranstormation efficiency of battery sheet 1, suppresses concavo-convex structure at battery sheet upper surface, makes its upper surface form nonplanar structure, thereby to increase relative light-receiving area.As shown in Figure 1, it is concavo-convex 2 that the surface of battery sheet 1 forms, and forms corrugated upper surface.Certainly, also can be that direct upper surface at the battery sheet is set to have male and fomale(M﹠F) structure salient point or concave point, thereby make the battery sheet have bigger light contact area.
With respect to original plate shaped battery sheet surface, in the utility model, the upper surface compacting of battery sheet is formed concavo-convex structure, thereby can effectively increase the light-receiving area of battery sheet, the concave-convex surface shape can strengthen solar cell to the absorptivity of incident ray to the diffuse reflection of light, effectively avoid line reflection, thereby can effectively improve phototranstormation efficiency.And after having suppressed sags and crests, because light angle increases, solar panels can be installed with wideer angular range, have avoided causing the reflection of light loss because of the setting angle error.Simultaneously, solar panels are in lamination process, and this has concavo-convex nonplanar structure, can strengthen the adhesion strength on surface, also can avoid greatly having bubble between solar watch surface layer and the encapsulating material, effectively surperficial thin-film material be positioned, avoid occurring fold.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
