Technical field
The present invention relates to technical field of solar batteries, particularly a kind of silver-colored conductive silver paste combination of the novel solar battery back of the body
Thing and preparation method thereof.
Background technology
At present, with the quickening of world energy consumption speedup, non-renewable energy resources have been gradually decreased, and the mankind are entering
In sector-style energy, water energy, the quick exploitation of nuclear energy and solar energy, wherein developing environmental protection the most, effectively and money especially with solar energy
Source is abundant, and crystal silicon solar photoelectricity development of projects main at present is the rapidest.Wherein, the main component of the back silver paste of application
Include function phase silver powder, inorganic binder (such as glass powder, oxide powder), organic binder bond, other solvent and
Additive.There are 2 shortcomings in the silver powder that current back of the body silver is taken, one is to use micro silver powder, i.e. silver powder to be generally micro nanometer silver more
Powder, the slurry fineness being made is larger, coarse, causes that the film layer in printing process is thicker, and compactness is bad, produces hole, print
Brush performance is bad, and then influences electric conductivity, and two be that silver powder content is higher, and the consumption to noble silver is larger, so that crystal silicon
Solar photovoltaic device industrial production cost is increased, therefore in this case, a kind of low silver of exploitation contains high performance crystal silicon too
Sun can carry on the back silver conductive paste and just be particularly important.
