Technical field
Present document relates to but be not limited to photovoltaic technology, espespecially a kind of photovoltaic module.
Background technology
Heterojunction amorphous silicon or crystal silicon solar batteries HIT (Hetero-junction with Intrinsic Thin
Layer, also known as HJT) it is one of several high performance solar batteries technologies of current main flow.Heterojunction amorphous silicon/crystal silicon solar
Battery has high transformation efficiency, low temperature coefficient, turns into the important directions that solar cell develops.
For heterojunction amorphous silicon/crystal silicon solar batteries, silver paste curing process and common crystalline substance after one side silk-screen printing
Silicon is different.This species diversity cause heterojunction amorphous silicon/crystal silicon solar batteries in series welding weld strength than relatively low.The opposing party
Face, when reducing shading-area, it can reduce on heterojunction amorphous silicon/crystal silicon solar batteries piece between main gate line and cell piece
Contact area, so that when welding is with main grid wire bonding, bonding area reduces, and welding pulling force reduces.
To sum up, for heterojunction amorphous silicon/crystal silicon solar batteries, weld strength is relatively low in correlation technique, influences to weld
Quality.
