By the glass substrate as made from embodiment one to six with being carried out by the property indices of traditional components soda-lime glass
Comparison, including coefficient of thermal expansion, strain point, liquidus temperature, fusion temperature, brittleness index and body resistivity, is specifically shown in down
Table：
As seen from the above table, the coefficient of thermal expansion of one to six glass substrate of embodiment existsBetween,
Strain point meets the performance requirement of CIGS thin film glass substrate used for solar battery at 560 DEG C or more.The heat of traditional soda-lime glass
The coefficient of expansion is met the requirements, but strain point is at 510 DEG C or so, in this way under 550~600 DEG C of baking, the dimensionally stable of glass
Property will significantly reduce, while the film layer of glass substrate upper surface can be come off due to glass deformation.
For glass metal viscosity be 10Pa.s when fusion temperature, the present invention in fusion temperature be less than 1500 DEG C, with sodium
Lime glass approaches, therefore difficulty and melted cost height etc. are clarified as caused by high temperature viscometrics there is no traditional glass substrate component and is asked
Topic.
In embodiment one to six, the value of MgO/CaO is 5~7.2, and brittleness index increases to 6500~6900m-1/2, this
The influence for meaning to scrape, scratch caused by extraneous factor can greatly reduce；And the brittleness index of traditional soda-lime glass reaches
To 7100~7530m-1/2, this is the easy range for generating and scraping and scratching, and traditional soda-lime glass is due to part caused by scuffing
Defect may increase with preparation process with last handling process.
In embodiment one to six, work as Na2O/K2When the value of O is more than 2.9, body resistivity reaches 1012.1~1013 ；
And traditional soda-lime glass body resistivity is 108.9~1011.7 , so the present invention is by adjusting Na2O/K2O values can make body electric
Resistance rate reaches the level of conventional glass substrate, while can effectively inhibit reacting between alkali metal and CIGS thin film material.
Na2O is fluxing agent, since it has larger impact to coefficient of thermal expansion, can effectively adjust the coefficient of thermal expansion of glass.This
Na in invention2O content is 10.3~13%, if content is less than 10.3%, meltbility is deteriorated, and homogenizing becomes difficult；If contain
Higher than 13%, coefficient of thermal expansion increases amount, and strain point reduces, and water resistance and chemical resistance are deteriorated, and suitable content is 10.3~
13%。
K2O is the composition for adjusting glass component high temperature and low temperature viscometric property, it by with Na2The melange effect control alkali metal of O
The migration of ion in glass influences the conductivity of glass.K in the present invention2The content of O is 1.31~3.9%, for practical glass
The strain point of glass improves the temperature with reducing glass melting, Na2O/ K2The value of O is preferably 2.5~10.
MgO can reduce the high temperature viscometrics of glass composition, increase low temperature viscometric property, can also increase the strain of glass composition
Point, the content of MgO if content is more than 6%, due to the reduction of high temperature viscometrics, can to clarify for 6~7.9% in the present invention
Process carries out at a lower temperature；If content is higher than 7.9%, since the reduction of high temperature viscometrics may cause glass liquidus curve
The increase of temperature, coefficient of thermal expansion can also reduce, and suitable ranging from 6~7.9%.
The effect of CaO is to MgO is similar, can also reduce the high temperature viscometrics of glass metal.If the content of MgO exists in a component
More than 6%, then the optimum range of CaO is 0~1.5%, if content is higher than 1.5%, glass metal easily crystallizes, model preferably
Enclose is 1.1~1.5%.
The optimum range of MgO/CaO is 5~7, if beyond this range, the scraping and wiping resistance performance of glass, i.e. brittleness refer to
Number can be reduced, and glass network is better than other alkaline earths to the affinity of MgO due to the Ar ion mixing effect between MgO and CaO
Metal oxide and small ionic radius can reduce the density of glass.
The above described is only a preferred embodiment of the present invention, not make limitation in any form to the present invention；Appoint
What those skilled in the art, without departing from the scope of the technical proposal of the invention, all using the side of the disclosure above
Method and technology contents make technical solution of the present invention many possible changes and modifications or are revised as the equivalent reality of equivalent variations
Apply example.Therefore, every content without departing from technical solution of the present invention, technical spirit according to the present invention do above example
Any simple modification, equivalent replacement, equivalence changes and modification, still fall within technical solution of the present invention protection in the range of.
