The material of the band that confluxes that the present invention relates to is generally copper.
It is one or more mixture in silver slurry, palladium-silver slurry, platinum silver slurry or other composition that the present invention is welded to connect the welding fluid that is adopted.
Terrestrial power generation solar battery sheet provided by the invention is different from existing battery sheet, and existing battery sheet main grid direction intersects vertically with thin grid, and the wire spoke of main grid is thick, generally at 1mm～2mm.The sensitive surface of solar silicon wafers provided by the invention forms the one or both ends of the thin grid of collecting light induced electron and adopts the mode of welding to be connected with the band that confluxes, and the direction that the band that confluxes is connected is identical with the thin grid line direction of battery sheet.
Terrestrial power generation provided by the invention solar battery sheet such as above-mentioned structure, main grid because of the no thick line width of cloth, the light-receiving area of battery sheet is bigger than existing solar battery sheet, and the band that confluxes that links to each other between the battery sheet is short, electric current displacement is short, and about 1/100 before being about, the electric quantity loss of battery chip module is die-offed, also saved the total amount of confluxing simultaneously, reduced the cost of manufacture of solar cell chip module with used copper.
With length * wide specification is 156mm * 156mm, and the battery sheet that 2 main grids are arranged is an example, and the wire spoke of main grid is 2mm, so the area of this battery sheet main grid is 2mm * 156mm * 2, and 2.56% of the entire cell sheet light-receiving area that accounts for.We suppose that the conversion efficiency of the battery sheet of existing standard is 16.4%, can reach as the conversion efficiency of the battery sheet of removing main grid: 16.4 * (1+0.256) %=16.82%.
Can calculate because the main grid of the thick line width of cloth causes the loss of this battery sheet electric weight by formula: the parameter of this battery sheet is difference: a=156mm, J=328.7A/m2,
Wf=90um, Hf=15um, Wb=Wtab=2mm, Hb=Htab=0.2mm, n=65, L=3mm.
Calculate according to formula, the battery sheet of each this specification of sheet has the loss of 0.1456W, mean that thus the conversion efficiency of former battery sheet that should specification is 16.4% (3.99W), owing to the conversion efficiency of the reason battery sheet of main grid finally shows as 15.8% (3.84W).
In order to verify the counter productive that main grid brought of the thick line width of cloth once more, the software-component that the present patent application people quotes Mitsubishi Utilities Electric Co. as proof to be provided is an example: the specification of this assembly is 50 * 156mm * 156mm, the conversion efficiency of every battery sheet is 15.6% (3.8W), yet the real transformation efficiency of battery sheet that provides of Mitsubishi Utilities Electric Co. is 16.2～16.4% in fact.This difference has the main grid of a lot of probe contact battery sheet just because of traditional cell tester, and electric current is low by the loss that probe is directly drawn when making the kwh loss of main grid in the test more than real work.In the battery that 3 main grids are arranged, this loss meeting diminishes, yet if there is the battery of 3 main grids to remove main grid, just can obtain more light-receiving area.In sum, remove the electric quantity loss that main grid brings, every battery sheet in the assembly can improve average 0.6% conversion efficiency.
The conversion efficiency of supposing the battery sheet of existing standard is 16.4%, because the light-receiving area that main grid brings and the loss of electric weight, the average conversion efficiency of battery sheet can reach 17.42% by removing.
So it is very significant that solar battery sheet provided by the invention has been removed the main grid of the thick line width of cloth.
Advantage of the present invention: the terrestrial power generation of the present invention main grid of solar battery sheet because of the no thick line width of cloth, the light-receiving area of battery sheet is bigger than the light-receiving area of existing solar battery sheet, improved the transformation efficiency of battery sheet, and the band that confluxes that links to each other between the battery strings provided by the invention is short, electric current displacement is short, before being about about 1/100, reduced the electric quantity loss of solar module significantly, also saved the total amount of confluxing simultaneously, reduced the cost of manufacture of solar cell chip module with used copper.
