LGI-DP- G-10
LASER EDGE ISOLATION SYSTEM
Introduction:
The decisive factor for solar cell performance is the minimization of recombination
Possibilities. In order to obtain high efficiency, front and rear side must be electrically isolated on the edges. The separation of p-type layers is done
By cutting trenches with QS-ND: YAG or QS-ND: Vanadate lasers. Compared to plasma etching, the productive advantages of laser scribing are better inline
Processing and improved material flow. Apart from that, there is no need for costly etching gases and their disposal. High power density is necessary in order to effectively eject the melt out of the kerf and to avoid re-deposition of the molten material.
Environment:
Occupy: Machine offers a installation bit for air-condition
Surroundings: It needs clean, no dust and no resonance source around.
Temperature: 55F(13C)to 82F (28C)
Humidity: 5% to 75%( free of condensed water).
Electrical source: 220VAC+/-5% 50Hz AC, capacity is over2KW. There is null line and absolute earth wire which should be well earth connection. It also equips specialized air-switch(specification: C32) and a creepage safeguard implement.
