When it comes to PV Interconnector, many people know this thing, but to say what is the use of interconnection belt, it is not necessarily everyone knows. In fact, to put it plainly, the interconnection tape is to connect the cells in series.
Photovoltaic solar interconnection tape can be said to be an important raw material in the welding process of solar modules, the outer surface are hot plating layer.
The selection criteria of PV interconnection tape is based on the thickness of the cell and the size of the short-circuit current to determine the thickness of the tape, the width of the interconnection tape should be consistent with the width of the main deletion line of the battery, the softness and hardness of the interconnection tape generally depends on the thickness of the cell and welding tools.
Manual welding requires the softer the state of the solder tape, the softer the state of the solder tape on the iron, the battery will come together after contact, and the stress generated during the welding process is very small, which can reduce the shattering rate. However, too soft solder tape will reduce the tensile strength and can be easily pulled off.
For automatic welding process, the welding tape can be slightly harder, so that it is conducive to the welding machine to straighten and compact the welding tape, too soft welding tape used in the machine is easy to deform, thus reducing the product yield.
