SNEC 15th (2021) International Photovoltaic Power Generation and Smart Energy Conference & Exhibition [SNEC PV POWER EXPO] will be held in Shanghai, China, on June 3-5, 2021. It was initiated and co-organized by Asian Photovoltaic Industry Association (APVIA), Chinese Renewable Energy Society (CRES), Chinese Renewable Energy Industries Association (CREIA), Shanghai Federation of Economic Organizations (SFEO), Shanghai Science & Technology Development and Exchange Center (SSTDEC), Shanghai New Energy Industry Association (SNEIA), etc.

As the most professional PV exhibition, CARMANHAAS showcases different solution for PV Optical laser System. Especially Non-destructive Dicing or Cutting.

Product advantages:

(1) The cell has no laser ablation damage, and the slot width: ≤20um. The slot length is less than 2mm. The crack surface is smooth without micro cracks.

(2) The solar cell basically has no heat-affected zone, which reduces the cell efficiency loss caused by cutting, and can increase the power of the module;

(3) The percentage of non-destructive cutting cracks decreased by 30%;

(4) No dust during cutting;

(5) Fragments and edges are less than 10um;

(6) The linearity of the lobes is less than 100um;

(7) Cutting speed is greater than 300-800mm/s.

Specifications:

Applications:

(1) Non-destructive cutting of photovoltaic cells, providing half-cell modules and three-cell modules, shingled components, plate interconnection components, seamlessly welded multi-bus grid main components

(2) Cell size: 156X156~215X215mm;

(3) Cell thickness: 140~250um;

(4) Compatible with P-type double-sided cells, N-type double-sided cells, and double-sided PERC Cells, etc.
