Technical field
The invention belongs to technical field of solar batteries, and in particular to a kind of aluminium paste used for solar batteries and its application.
Background technology
Crystal silicon solar batteries clean reliable regenerative resource as a kind of, are increasingly paid attention to by various countries, are state
The focus of border research, lifts the photoelectric transformation efficiency of crystal silicon solar batteries, is to promote photovoltaic generation to come into having for huge numbers of families
Try hard to keep barrier.Aluminium paste has longer history, at present the aluminium paste of the overwhelming majority as a kind of metal paste in the application of crystal silicon battery
Good back surface field effect is all pursued after sintering, and solid solubility of the aluminium in silicon is relatively low, it is difficult to play preferable back surface field effect.
Solid solubility of the boron in silicon is higher than aluminium an order of magnitude, therefore is used for doing additive by numerous aluminium paste enterprises, to
The higher back surface field of doping concentration is obtained after aluminium paste sintering, but no matter uses pure boron or compound boron additive, is failed
Play expected effect.
The content of the invention
, can be in back surface field area after aluminium paste sintering it is an object of the invention to provide a kind of aluminium paste used for solar batteries and its application
Domain forms high concentration and uniform boron or gallium back surface field, greatly improves the conversion efficiency of solar cell.
For achieving the above object, present invention employs following technical scheme：
A kind of aluminium paste used for solar batteries, it is characterised in that by weight percentage including following components：
The additive is the silica flour for electroactive boron or gallium active boron containing high concentration electric or the gallium being entrained in silicon, boron or
Doping concentration of the gallium in silicon is 1019-1021atoms/cm3.The silicon function as carrier carry the boron of activation or
Gallium.
Further, the one of the boron or gallium is first entrained in silicon, then doped silicon again with magnesium or the one high temperature of aluminium
Alloyed powder is made in melting, and the alloyed powder is used to substitute the aluminium powder.
After alloyed powder is made, alloyed powder easily forms stable homogeneous as the component in aluminium paste during high temperature Fast Sintering
Conductive phase, obtain relatively low resistance.
The alloyed powder forms silicon doping by will first be mixed under boron or gallium high temperature in silicon, doped silicon melts with magnesium or aluminium again
Melt and alloyed powder is made, not doped silicon mixes with magnesium or the simple and mechanical of aluminium.
Further, the boron or gallium are electrically activated with silicon in vacuum or protective gas by high-temperature fusion, temperature
Spend for 1420 DEG C -1550 DEG C.
Further, the additive is the globular powder that particle diameter is 0.5~15um.
The particle diameter of the additive be advantageous within this range additive with aluminium paste other compositions it is tightly packed, simultaneously
It will not cause to print network blocking version again.
Further, the surfactant is Disper655.
Further, the purity of the silicon is 5N.
Further, the organic carrier includes one in terpinol, butyl carbitol acetate, diethylene glycol monobutyl ether
Kind or it is several, it is EC150 (3%-5%) that ethyl cellulose is added after well mixed, rilanit special (0.5-2%), stearic acid
(0.5-2%), it is dissolved under 80 DEG C of temperature conditionss integral.The effect of the organic carrier is to ensure that aluminium paste has good print
Brush performance.
It is a further object of the present invention to provide a kind of solar cell, it is characterised in that aluminium paste prepares gained from the above mentioned
Operation principle of the present invention is as follows：
Electroactive boron or gallium additive in aluminium paste of the present invention, boron or gallium therein before being acted on aluminium, first and
Silicon forms electroactive displacement doping.In temperature-fall period is sintered, the electroactive boron or gallium separate out with carrier silicon, in silicon chip
Solid liquid interface epitaxial growth, the boron or gallium back surface field of formation can effectively reduce that back surface is compound, can greatly improve opening for battery
Pressure, its electroactive boron or gallium concentration of the silicon carrier of the activation boron containing high concentration can reach 1019~1021atoms/cm2, can be made with this
Obtain a series of additives containing active boron or gallium.Contain high concentration electric active boron in this additive, its group as aluminium paste
Point, the boron or gallium back surface field of high concentration can be formed in back surface field area after sintering, greatly improve the conversion efficiency of solar cell.
Invention advantage：
The boron or gallium back surface field of high concentration can be formed in back surface field area after aluminium paste sintering used for solar batteries of the present invention, made
The conversion efficiency of solar cell greatly improves.
