Photovoltaic Cell Laser Processing Optical Components


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.





Optical Lens For Onsolar Cell


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.
