Wet Wafer Separator 3000+
26
Automation and Integration are key factors to cut costs in photovoltaic industry. With the Wet Wafer Separator AMB Automation presents a new solution in separation of wafers.
High throughput up to 3000 wafers per hour and marginal breakage rates are features of the new separating system. Even thinnest wafers can be handled safely and without mechanical stress. The system automatically identifies fractures and sorts out double wafers. Productivity is guaranteed by a buffer system and continuously refreshed water bath facilitates consistent system uptime. Besides fully automated separation, the wafers can be tracked easily. AMB Automation offers new process solutions and guarantees you constantly high throughput.

Rotatable sputter target materials
Bekaert is building on its success of introducing rotatable sputtering technology in glass and photovoltaic applications by developing a new range of rotatable sputter target materials for the deposition of TCO layers used in PV cells.
TCO layers are essential building blocks for all thin film PV (amorphous silicon (a-Si), cadmium telluride (CdTe) and CI(G)S applications, where optical transmission and electrical conductivity are required simultaneously. Bekaert’s rotatable sputter targets are one-piece targets, allowing a more stable process. Bekaert has added to its TCO portfolio a new target material – AZO, Zinc Oxide doped with Aluminum oxide (1-2 wt%). Other target materials available from Bekaert for the PV
market include ITO (e.g. In2O3 :Sn), Al, Mo, High Purity Si, ZnAl,
ZnSn, and custom-made alloys. “Bekaert’s innovation, heavy investment in R&D, exemplary customer service and comprehensive understanding of customers’ applications led to the company’s market-leading position in rotatable sputter solutions for automotive and architectural applications. We’ll be adopting the same approach in the PV market.” says Koen Staelens, Product Market Manager of Bekaert Sputter Products. “Having the right customized sputter hardware solutions and developing the right rotatable sputter target materials will allow us to meet the demands of the photovoltaic market. We’re eager to meet up with industry experts and decision makers at various shows and explore new business opportunities.”
Lowest Cost of Ownership & Highest Yield
140,000 man hours per year of potential savings for operating costs in comparison to manual separation
98 %1 machine uptime for a breakage rate of 0.1% results in 0.5% less wafer loss = $ 4,000,000 savings per year
1,200 operating hours per year of potential savings due to optimised interfaces between wafering and separation
0.5% less wafer loss due to prequalification produces additional potential savings of $ 4,000,000 per year.
A special feature of the 3D-Micromac roll-to-roll technology is the laser processing of substrates on the fly. That means a continuous winding process for reaching of a very high throughput. The winding speed is around 17 to 170 meters per minute. Different flexible substrates (paper or foil) can be processed with the system. The integration of different laser sources - based on customer’s requirements - is possible. Even films with different characteristics for instance solar cells, sensors, actuators, and electronics - on polymer base - can be processed.
