Abstract
A kind of self-cross linking type acrylic system, it is the mixed system of acrylic monomers and acrylic crosslinking agent.The acrylic system of the present invention has preferable controlled compatibility, new interface layer can be formed on the surface of electrocondution slurry, the levelability of effective lifting electrocondution slurry, the phenomenon of the disconnected grid occurred when making electrode using the electrocondution slurry can be effectively reduced, so as to improve the photoelectric transformation efficiency of cell piece.In addition, during sintering is dried, double bond in acrylic system can form the unstable living radical containing unpaired electron, the living radical can form stable covalent bond with the electronic coupling in the double bond of neighbouring acrylic monomers or acrylic crosslinking agent, and produce new free radical, so move in circles, the thermosetting polymer with tridimensional network can be formed, so as to improve the plasticity of electrocondution slurry, avoid occurring the phenomenon that grid line caves in drying course, so as to improve the photoelectric transformation efficiency of cell piece.
Description
Technical field
It is used for the self-cross linking type acrylic system of solar cell conductive paste the present invention relates to a kind of.
Background technology
In recent years, in photovoltaic art, more than 90% solar cell is silicon solar cell.Silicon solar cell
The technological progress of photovoltaic art is greatly facilitated in extensive industrialization.The front electrode (positive electrode) of silicon solar cell is used as it
Important component, main function is collected current.Light-receiving area and series resistance of the front electrode to silicon solar cell
There is conclusive influence, therefore, front electrode is to influence one of key factor of conversion efficiency of solar cell.
Conducting paste for silicon solar cell mainly includes positive electrode silver paste, back electrode silver paste and back electrode aluminium paste.Wherein,
Positive electrode silver paste is used for the front electrode for making silicon solar cell.In photovoltaic industry, silicon solar cell front electrode leads to
It is made, electrocondution slurry is printed on silicon chip frequently with screen printing technique with wire cloth, then passes through Fast Sintering work
Skill formation front electrode, can so make front electrode and silicon base have good Ohmic contact.And without net netting version because thin
Without net knot in grid line, and strike through is good, and line footpath is smooth after printing, narrow width, can be obviously improved the opto-electronic conversion of cell piece
Efficiency, therefore can produce the front electrode of better performances without net netting platemaking technology.
However, due to smaller without the net netting thin grid perforate of version, and line footpath is general at 27 μm~29 μm so that existing positive electricity
Easily there is disconnected grid phenomenon in printing process in pole silver paste.In addition, the line footpath of the printing grid line without net netting version is narrow and prints grid
