Utility model content
In view of this, the utility model provide one kind can bonding photovoltaic cell, solve problems of the prior art,
Concrete scheme is as follows：
One kind bonding can connect photovoltaic cell, including cell matrix, described cell matrix front be provided with thin grid and and with
The vertical positive main grid of described thin grid, the back side of described cell matrix is provided with aluminium film and back of the body main grid it is characterised in that described back of the body main grid
Respectively there is one with described positive main grid, described back of the body main grid and described positive main grid set the opposite sides being respectively provided at described cell matrix.
Further, the width of described back of the body main grid and described positive main grid is equal.
Further, described aluminium film overlays on the overall back side of described cell matrix, and described back of the body main grid overlays in described aluminium film,
Described back of the body main grid is less than described aluminium film, forms positive main grid groove between the top of described back of the body main grid and the described aluminium film exceeding.
Specifically, described positive main grid slot space size is more than or equal to the bulk of described positive main grid.
Specifically, described positive main grid starches printing for fine silver.
Preferably, the width of described positive main grid is 0.8-2mm.
Preferably, the width of described positive main grid is 1mm or 1.5mm or 1.8mm.
Preferably, described thin grid quantity is 80-120 root.
The utility model this have the advantage that：The main gate line number of electrodes that cell piece itself adopts is less than general components, electricity
Pond light-receiving area itself increases, and generating efficiency improves.Can be by positive main grid and back of the body main grid bonding between cell piece and cell piece
Mode realize connecting, it is to avoid due to the quality problems of the various assemblies that welding skew brings, make the series electrical of assembly simultaneously
Resistance reduces, the electrical property of lifting assembly.
