Above solar battery sheet 1 existing expensive reaching hanged down battery conversion efficiency, also has influence on the whole cost and the overall performance of the solar panel that is packaged with prior art solar battery sheet 1.
Summary of the invention
The purpose of the utility model is for providing a kind of solar battery sheet, the technical problem that production cost is high, battery conversion efficiency is low that exists with the solar cell that solves prior art.
Another purpose of the utility model is that a kind of solar panel with the utility model solar battery sheet is provided.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
A kind of solar battery sheet, the back side of this solar battery sheet have two parallel backplates, and each said backplate is made up of a plurality of segmented electrodes of straight lines altogether, and each said segmented electrode length is identical, and the gap length between each said segmented electrode is identical.
The solar battery sheet of the utility model, preferred, each said backplate is made up of 3 to 8 segmented electrodes.
The solar battery sheet of the utility model, preferred, be filled with aluminium paste in the said interval between the said segmented electrode.
The solar battery sheet of the utility model, preferred, each said backplate is made up of 8 segmented electrodes.
The solar battery sheet of the utility model, preferred, the length of said battery sheet and the wide 156mm that is, the length of said segmented electrode is 6-13mm.
The solar battery sheet of the utility model, preferred, the length of said segmented electrode is 12.45mm, the gap length between each said segmented electrode is 6.55mm.
The solar battery sheet of the utility model, preferred, the width of said segmented electrode is 2-3.5mm, the spacing of two said backplates is 75mm.
The solar battery sheet of the utility model, preferred, the width of said segmented electrode is 3mm.
The solar battery sheet of the utility model, preferred, the length of said segmented electrode equals the said gap length between the said segmented electrode.
The solar panel of the utility model is packaged with the solar battery sheet of the utility model in the said solar panel.
The beneficial effect of the utility model is; The solar battery sheet of the utility model carries out segmentation with the continuous type backplate of the solar battery sheet of prior art, is divided into independently a plurality of segmented electrodes; Fill with aluminium paste at interval between the segmented electrode; Thereby reduced the silver slurry use amount in the solar battery sheet production process, reduce the production cost of solar battery sheet, and then reduced the production cost of solar panel.In addition,, thereby increased the area of the aluminium back of the body field of solar battery sheet, improved the open circuit voltage of solar battery sheet, promoted battery conversion efficiency owing to fill with aluminium paste at the interval between the segmented electrode.
Description of drawings
Fig. 1 is the schematic rear view of the solar battery sheet of prior art.
Fig. 2 is the schematic rear view of the solar battery sheet of the utility model preferred embodiment.
Embodiment
The exemplary embodiments that embodies the utility model characteristic and advantage will be described in detail in following explanation.Be understood that the utility model can have various variations on various embodiment, the scope of its neither disengaging the utility model, and explanation wherein and accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the utility model.
The solar panel of the utility model embodiment is packaged with the solar battery sheet of the utility model embodiment.But the application of the solar battery sheet of the utility model is not limited to solar panel, and can be applied on other solar cell goods with solar battery sheet.
Following mask body is introduced the solar battery sheet of the utility model preferred embodiment.
As shown in Figure 2; The solar battery sheet 1 of the utility model embodiment; Its back side has two parallel backplates 6; Each backplate 6 is made up of 8 segmented electrodes 5 that are total to straight line (promptly on same straight line), and the length of each segmented electrode 5 is identical, and the length at the interval 4 between each said segmented electrode is also identical.
When making the solar battery sheet 1 of the utility model; Can be according to the position of the test probe of the testing apparatus of test solar battery sheet 1 performance; Confirm the segments and the residing position of each section of backplate 6, segmented electrode 5 is a silver electrode, and the interval 4 usefulness aluminium pastes between the segmented electrode 5 are filled; Thereby changed the figure of the aluminium back of the body field 3 of solar battery sheet 1, increased the area of aluminium back of the body field 3.The aluminium that increases solar battery sheet 1 is equipped with the area of field 3, can increase the absorption of solar battery sheet 1 for infrared light, thereby increases the open circuit voltage of solar battery sheet 1, improves battery conversion efficiency.
(unit: solar battery sheet 1 mm) is an example, specifically introduces the layout of segmented electrode 5 with 156 * 156 below.
As shown in Figure 2, each backplate 6 is made up of 8 segmented electrodes 5, and the length of each segmented electrode 5 is 12.45mm, and width is 3mm.The length at the interval 4 between the segmented electrode 5 is 6.55mm.The high order end of leftmost segmented electrode 5 is 5.28mm apart from the distance of solar battery sheet 1 left hand edge.Centre-to-centre spacing between two backplates 6 is 75mm, and the distance of last end distance solar battery sheet 1 top edge of the backplate 6 of upside is 39mm, and the distance of following end distance solar battery sheet 1 lower limb of the backplate 6 of downside also is 39mm.
