Abstract

The utility model discloses a solar battery component, comprising a frame, a glass top plate, battery pieces and a back plate, wherein the glass top plate, the battery piece and the back plate are arranged in the frame; bus bars are arranged among all the battery pieces; and a gap is left on the back plate and is internally provided with a reflecting structure for reflecting the sunlight. The solar battery component can enable the sunlight irradiated on the gap of the back plate to be reflected on the battery pieces, and enable the battery pieces to absorb the sunlight furthest, thus improving the photoelectric conversion efficiency of the battery component.

Description

A kind of solar module
Technical field
The utility model relates to a kind of solar module that can improve the efficiency of light energy utilization, belongs to area of solar cell.
Background technology
At present, the lasting use of conventional energy resource has brought a series of economy and social concerns such as energy scarcity and ecological deterioration, the development solar module be address the above problem by way of one of.Therefore, countries in the world are all at the active development solar module, and high conversion efficiency, low cost are the solar module main development tendency, also are the targets that technical research person pursues.
Existing solar module mainly comprises framework 1 and is located at framework interior glass top plate 2, battery sheet 3 and backboard 4 referring to shown in the accompanying drawing 1, also is provided with busbar 5 between each battery sheet.When above-mentioned solar module was worked, to the gap of battery sheet and backboard, direct projection was absorbed by the battery sheet to battery sheet glazing light, and then is converted into electric energy by the glass top plate direct projection; And the light of direct projection to the backboard gap, because the surface in gap generally is planar structure on the backboard, light directly reflects away, and is not utilized by the battery sheet, this part light source has just been wasted, shown in Fig. 2~3; The zone in above-mentioned gap mainly comprises between frame and the battery sheet, between battery sheet and the battery sheet, between busbar and the battery sheet, between busbar and the frame; And in the battery component of existing structure, the gross area in above-mentioned gap accounts for 4~7% of the battery component gross area, therefore, how effectively to utilize this part light source also to obtain those skilled in the art attention gradually.
Summary of the invention
The utility model purpose provides a kind of solar module, to make full use of this part light source that shines on the assembly internal clearance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of solar module, comprise framework and be located at framework interior glass top plate, battery sheet and backboard, also be provided with busbar between each battery sheet, have the gap on the described backboard, be provided with the catoptric arrangement of reflected sunlight in the gap of described backboard.
Above, the gap on the described backboard mainly comprises as lower area: between frame and the battery sheet, between battery sheet and the battery sheet, between busbar and the battery sheet, between busbar and the frame.
In the technique scheme, described catoptric arrangement is the pyramid suede structure.This similar is in the pyramid suede structure of silicon chip surface, to increase the absorption of light.Used material can be fluorine material, amide-type material or metal material, and as polyvinyl fluoride, polyimides or silver, it has good weatherability, is difficult for aging and xanthochromia.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model is provided with the catoptric arrangement of reflected sunlight in the gap of backboard, thereby the sunray that will shine on the backboard gap reflexes on the battery sheet, make the battery sheet farthest absorb sunray, improved the photoelectric conversion efficiency of battery component, experimental results show that: compare with existing battery component, adopt the photoelectric conversion efficiency of the battery component of this structure can improve 2~4%, have significant good effect.
2, the pyramid suede structure of the utility model employing has outstanding reflecting effect, adopts fluorine material or the amide-type material with good weatherability properties simultaneously, is difficult for aging and xanthochromia, makes battery component have the useful life of length.
3, the utility model is simple in structure, is convenient to preparation, is suitable for applying.
