It is limited, and China's traditional fossil energy reserves are far below world average level；On the other hand, with people's environmental protection ideas
Continuous reinforcement, the trend of future source of energy development is had become to the exploitation of clean and environmental protection renewable energy, and solar energy is a kind of
Inexhaustible renewable energy is seized of consequence in the long-term energy strategy in China；At present to the benefit of solar energy
With mainly by crystal silicon solar batteries power generation, solar battery positive silver paste is prepare solar battery very important
One of raw material, it is mainly used for making solar battery front side main grid, and main function is the electricity that will be collected in solar battery
Stream is imported and is exported；It mainly include silver powder, glass powder, organic adhesive etc. in solar battery positive silver paste.Solar-electricity
Although the specific gravity that the positive silver glass powder in pond accounts in solar battery positive silver paste is little, since glass powder is as solar battery
Binder Phase in positive silver paste can play the antireflective film for corroding silicon chip surface layer, bonding silver powder and silicon wafer, increase Argent grain and silicon
The contact on piece surface promotes silver powder with silicon substrate the effects of reaction, therefore the quality of the positive silver glass powder performance of solar battery
It will have a direct impact on the quality of solar energy positive silver paste, to affect the transfer efficiency of solar panel indirectly.
Although the city of domestic silver paste accounts for rate and gradually riseing, by 2018, Germany congratulated Li Shi, Dupont, South Korea
Samsung, TaiWan, China four large manufacturers of large standing grain etc. still in occupation of 60% or more the market share, and constantly sending out always
Exhibition progress；Domestic silver paste manufacturer starts late, although having certain batch by feat of technological accumulation in recent years
Availability, but domestic positive silver-colored market is mostly also to rely on import, and this is difficult to the manufacturing cost of solar battery always
Decline, constrains the market competitiveness and development of domestic solar battery enterprise to a certain extent.
Summary of the invention

The raw material of the unleaded positive silver glass powder forms and its mass percent are as follows: Bi20367%, B2O321.5%, SiO2
3.6%, Al2O35%, ZnO 1.6%, Na2O 0.5%, CeO2 0.8 %。
The raw material of the unleaded positive silver glass powder forms and its mass percent are as follows: Bi20377%, B2O310%, SiO2
3%, Al2O34%, ZnO 4%, Na2O 0.5%, K2O 0.5%, CeO2 1 %。
A kind of preparation method of the positive silver glass powder of lead free solar cell, the specific steps of which are as follows:
(1) glass powder molten batch material is pressed into Bi20367 ~ 81.5%, B2O32.1% ~ 21.5, SiO20 ~ 10%, Al2O3 4%~
8%, ZnO 1.6% ~ 5.2%, Na2O 0 ~ 1%, K2O 0~1%, Li2O 0 ~ 1%, CeO20.2% ~ 1.2% proportional arrangement is good；
(2) all batches are sufficiently stirred, are uniformly mixed it, then uniformly mixed raw material is put into the corundum earthenware of drying
In crucible, and it is put into 55 ~ 70 min of melting in 1100 DEG C of high temperature furnace；
(3) crucible is taken out from resistance furnace, the glass metal after 1100 DEG C of meltings is poured into rapidly and carries out water quenching in cold water,
It goes after water to carry out drying and processing to glass dregs and crucible, obtains solid glass little particle；
(4) resulting glass little particle is put into airflow milling and is ground, 0.5 ~ 0.9 MPa of operating air pressure, classification wheel speed 260 ~
300 r/min are put into drying in drying box, obtain solar battery back silver glass powder after grinding.
The effect of each oxide is as follows in the present invention:
Bi2O3In glass as network intermediate and with [BiO3] and [BiO6] structure type exist, bismuthate glass is
A kind of system most strong instead of structure in lead glass system, chemical stability is best；Increase Bi2O3Content can reduce glass
Softening temperature increases the coefficient of expansion of glass, but Bi2O3Too high levels, which also result in, is difficult to be formed complete glass, therefore
Bi2O3Content is set as 67% ~ 81.5%.
B2O3In glass as Network former and with [BO3] and [BO4] structure type exist, when the system glass
In, work as B2O3When content is lower, B2O3Mainly with the [BO of plane trigonometry body structure3] form presence, so that glass glues at high temperature
Degree reduces, and reduces glass powder fusing point, but with B2O3The increase of the content, [BO of plane trigonometry structure3] four sides can be gradually transformed into
[the BO of body structure4], bridging oxygen number of keys increases, and increases the fusing point of glass；Therefore B2O3Content is set as 2.1% ~ 21.5%.
SiO2In glass as Network former and usually with [SiO4] structure type exist, can be improved glass
Chemical stability, but due to SiO2Middle Si-O bond energy is larger, as SiO in glass2It will cause the fusing point liter of glass when content is excessive
Height, therefore SiO in system2Content is set as 0 ~ 10%.
Al2O3Exist in the form of intermediate oxide in glass, is properly added a small amount of Al2O3The glass of glass can be improved
Glass degree also has certain facilitation, but Al to the thermal stability and chemical stability of glass2O3Content excessively will lead to
There is split-phase, therefore Al in the system glass2O3Content is set as 4% ~ 8%.
ZnO is used as intermediate oxide and in glass with [ZnO6] and [ZnO3] structure type exist, due to Zn2+?
It is strong larger, " free oxygen " can be robbed and form [ZnO3] tetrahedron, participating in glass network structure must form, when ZnO content is lower
When, ZnO is mainly with [ZnO3] tetrahedral geometry presence, mainly play net mending, the network structure of glass can be improved, make chemistry
Stability enhancing, moreover it is possible to which the thermal expansion coefficient for adjusting glass mainly plays suspension when ZnO content is more, excessive
ZnO can also reduce the uniformity of glass, may promote the split-phase and crystallization of glass；Therefore ZnO content is arranged 1.6% ~ 5.2%.
CeO2Middle Ce is valence variation element, and under the high temperature conditions, the valence state of Ce can change, and becomes+trivalent from+4 valences, and
Oxygen is released, provides the atmosphere aoxidized partially to system, while certain clarification can also be played.Its mechanism of action
It can be indicated with following equation:
K2O and Na2O and Li2O is alkali metal oxide, will increase the leakage current of silicon solar cell when content is excessive, individually
Alkali metal content increase will also result in the stability decline of glass, but the thermal expansion of the adjustable glass of alkali metal oxide
Coefficient and softening temperature, and be added by two or three of alkali metal mixing, enhancing glass can be played using its " double alkali effects "
The thermal stability of glass and the effect of chemical stability, therefore in the glass frit, K2O and Na2O and Li2O mass fraction is 0
~1%。
The present invention proposes a kind of high-performance Pb-free solar energy positive silver glass powder and preparation method, which uses bismuthic acid
Salt glass system, it is nontoxic, meet environmentally protective requirement, and better performances, cost of manufacture are cheap；The just silver-colored glass of solar battery
During the high temperature melting of glass powder, using 1050 DEG C ~ 1200 DEG C of glass melting temperature, in the premise of the abundant frit reaction of preparing glass charge
Decline low temperature so that more energy efficient, when the temperature of resistance furnace is lower than 1050 DEG C, cannot sufficiently be melted between the batch in crucible
Melt reaction, when the temperature setting of resistance furnace is 1200 DEG C or more, glass metal increases the erosion of crucible, and the higher consumption of temperature
Can be more, it is unfavorable for production energy conservation, therefore glass batch mixing is placed on 1050 DEG C ~ 1200 DEG C of resistance furnace in the present invention
Middle melting.
