Moreover, yield declines and the risk of damages to the boats as a result of improper handling are also minimized.

Advantages Time savings for regular maintenance work Reduced risk of damaging components Cuts down the number of boats per system thanks to the reduced cleaning times Boat pcvd can be performed at higher temperatures Minimized penetration of etching residues into reactor chamber Yield losses resulting from inaccurate boat installations are prevented.

Availability Upgrade solution ready for shipment with short delivery times. It also highlights that new capacity from new entrants is still being based upon pecvx existing c-Si mono and multi process flows, and not moving to more exotic cell concepts. The tube systems ensure the creation of an extremely efficient and homogeneous anti-reflective coating using a direct plasma deposition process, which is limited in scope and comprises only the wafers and graphite boats, whereas process tubes are only marginally affected by parasitic deposition.

One of the noteworthy benefits of the tube system is its flexibility, which accommodates varying production capacity utilization loads and ensures that the system will operate continuously while maintenance work is being performed or individual process tubes are shut down.

The system is available in numerous different versions and can be configured to meet the specific process and capacity requirements, as well as varying degrees of automation. I would like to receive information from carefully selected 3rd parties that may have products and services of interest to me.

Finlay Colville, vice president of NPD Solarbuzz told PV Tech that the expansion plans from Shaanxi Youser went back several years, with key equipment suppliers having waited for some time to get the first orders. Aluminum Oxide AlOx with its excellent passivation properties and high negative centdotherm charge density is perfectly suited to achieve this.

AlOx PERC Technology

The tube system is capable to manufacture stacked layers within one process, which is required for PERC applications and proven for graded layers centrohherm as AR-coatings in standard cells. In practice, this is basically decoupling many from the threat of any overseas trade restrictions and provides a safety net for the banks offering loans to the manufacturing segment.

centrotgerm The new patented centrotherm process boats dispense with the need for dismantling and thereby allows our customers to save a good deal of time and added staff.

Keep me signed in. This dispenses with periodic reactor cleaning and increases equipment availability. Given that the deposition is limited to centrotnerm wafers and graphite boats, the process tubes are only marginally impacted by parasite coating and have to be cleaned fairly once a year. Excellent passivation characteristics Integrated surface conditioning good adhesion, no blistering Variable process sequences for multiple and graded layers High availability thanks to redundancy and short cycle times Up pecvvd 5 independently operated quartz tube reactor chambers Fully automated boat transport Water cooling system prevents thermal interference between different tubes The modular design facilitates installation and start-up as well as the integration into existing production lines.

Here is a preview. Pre-requisite for a successful implementation is a highly efficient surface passivation of front and rear side. As a rule, the cleaning and re-etching of the process boats is costly and time consuming since they have to be disassembled and reassembled. Furthermore, these stacks are deposited in one run and in one step, by just changing the recipe. The central innovations include modified ceramic and graphite spacers with included purge channels.
