Background technology
Global fossil energy crisis has promoted the fast development of photovoltaic industry with environmental pollution.At present, with crystal silicon electricity
Component based on the piece of pond occupies more than the 80% of global photovoltaic module market；Crystal-silicon battery slice is developed so far, its cost of manufacture and
Generated energy turns into the main restricting factor of its development.In terms of cost of manufacture, silicon materials in occupation of about 60-70% material cost,
Material cost of the consumption of silver paste in occupation of about 15-25%；So the cost of high-purity crystal silicon material and its usage amount, Yi Jiyin
The usage amount of slurry all has significant effect to the cost of cell piece or component.In terms of generated energy, it is mainly by solar-electricity
The influence of the effective illuminating area of pond piece and photoelectric transformation efficiency；The photoelectric transformation efficiency heavy dependence crystal silicon material sheet of cell piece
The structure of body, effective illuminating area of cell piece is to depend on cell piece master, the area coverage of thin grid line.
The generating matrix of crystal-silicon battery slice is silicon chip, conventional cell piece be printed on the thin grid line of many bars to collect silicon chip by
The electric current produced after to illumination, and 2-5 bars main gate line is also printed on to collect the electric current on thin grid line.In low cost, high generating
Under the urgency for measuring this target of cell piece, dereliction grid line cell chip technology arises at the historic moment.Dereliction grid line cell piece, generally referred to as
On the basis of conventional batteries piece, remove main gate line and retain thin grid line；This cell piece, on the one hand can be significantly because without main gate line
The usage amount of silver paste is reduced, can additionally increase effective illuminating area of cell piece.
When dereliction grid line cell piece carries out component production, how to ensure the generated energy of monolithic battery piece, meanwhile,
Welding the later solar components that are together in series also can all play the generating capacity of cell piece, be urgently to be resolved hurrily at present ask
Topic.
The content of the invention
The purpose of this utility model is to provide a kind of based on dereliction grid cell piece, does not change existing component production technology
, reduction production cost and raising generated energy are without main grid crystal-silicon battery slice solar components.
In order to achieve the above object, the technical solution adopted in the utility model is：One kind without main gate line crystal-silicon battery slice too

Thin grid line can solve the problems, such as the rosin joint of TC agings, disconnected grid.
The size of main gate line reserve part is that length is that 10mm width is 0.6mm.
The thin grid line termination of rectangle, the thin grid line of overstriking and main grid reserve part are corresponding 4 groups or 5 groups.
Crystal silicon solar batteries piece it is main by：Light is converted into the conductive material of electric high-purity crystal silicon material, collected current
Including positive main gate line, the silver electrode of thin grid line and the back side, aluminium backboard, key point of the present utility model is to remove cell piece
Most of main gate line and retain the fraction at its two ends.Calculated according to current cell piece material cost, silicon materials account for 60-
70%, silver-colored consumption accounts for 15-25%；And silver usage amount in terms of on, the silver amount of front electrode is relatively good, backplate quality
Not as front, generally positive fine silver, the silver-aluminium alloy at the back side, therefore the utility model reduces positive master
The silver-colored consumption of grid line, greatly reduces production cost.
According to the related experiment carried out as foundation, the other performance of this cell piece reaches the equal water of prior art
It is flat, the design based on this cell piece, we both ensure that the generating effect and reliability of cell piece and component, reduction cell piece
Cost and improve its generated energy.Wherein, the removal of main gate line can reduce 50%-the 70% of front side silver paste usage amount, it is possible to decrease electricity
10%-the 21% of the cost of pond piece；Illustrated with more intuitive data, calculated by 10 megawatts of photovoltaic plant of generated energy, Ke Yijie
About nearly 230-380 ten thousand yuans of material cost.In addition, in terms of generated energy, the removal of main gate line and coordinate special welding
Use, it can increase 1%-the 2% of generating efficiency；Illustrated with more intuitive data, counted by 10 megawatts of photovoltaic plant of generated energy
Calculate, annual electricity generating capacity can at least increase by 30-60MW.
The utility model is in actual production process, it is only necessary to can be produced the progress transformation of printed portions half tone,
Original production technology is not changed, will not increase production cost.
The connected mode of polylith cell piece, which remains unchanged, uses Series connection welding, without changing welding material and need not change component
Production technology and equipment.
Therefore the utility model is performed to most preferably by the efficiency of dereliction grid cell piece, is reduced cost, is improved generating
