Aluminum Oxide AlOx with its excellent passivation properties and high negative fixed charge density is perfectly suited to achieve this. Subscribe me to PV-Tech Newsletter. 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 drying can be performed at higher temperatures Minimized penetration of etching residues into reactor chamber Yield losses resulting from inaccurate boat installations are prevented.

Pre-requisite for a successful implementation is a highly efficient surface passivation of front and rear side. There was risk that when spending returned, there would be pressure on Chinese manufacturers to effectively keep the money inside China and use domestic tool suppliers that entered the PV industry back in It also highlights that new capacity from new entrants is still being based upon copying existing c-Si mono and multi process flows, and not moving to more exotic cell concepts.

Thanks to its excellent process flexibility, the tube system is not only a perfect solution for nitride coating processes, but also for the realization of highly efficient solar cell concepts, such as PERC or PID free solar cells. I would like to receive information from carefully selected 3rd parties that may have products and services of interest to me.

Cenrrotherm Shaanxi Youser order for centrotherm is also notable as the company highlighted that it was the single largest equipment order the company had received since exiting restructuring activities. Solar Media Energy Storage News.

Solar Media Energy Storage News. However, according to Colville the move by Shaanxi Youser to expand capacity has other implications. Subscribe me to PV-Tech Newsletter. Sign Up Sign In.

Renewable Energy India Expo. Here is a preview. Keep me signed in. 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. By adding this hardware kit, all centrotherm PECVD systems can easily be upgraded with minimum space requirements.

Consequently, preparing the boats for re-etching consists only of the partial loosening of a few connecting pins, while the overall structure of the boat remains unchanged.

I would like to receive information from carefully selected 3rd parties that may have products and services of interest to me. Given that the deposition is limited to the wafers and graphite boats, the process tubes are only marginally impacted by parasite coating and have to be cleaned fairly once a year. Renewable Energy India Expo. The stack is compatible with standard Al pastes and shows a high passivation quality after contact firing. This is seen, not just in a new entrant adding hundreds of megawatts, but also in the many tier 2 and tier 3 Chinese suppliers that have restarted operations, or ramped up lines dormant for more than 18 months.

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.

AlOx PERC Technology

Moreover, yield declines and the risk of damages to the boats as a result of improper handling are also minimized. The centrotherm PECVD system requires a comparatively small footprint and delivers the lowest overall cost of ownership in the segment thanks to the maximum utilization of process gases.

We send out a daily email newsletter with the latest in depth news and analysis. The tube system is capable to manufacture stacked layers within one process, which is required for PERC applications and proven for graded layers such as AR-coatings in standard cells. Furthermore, these stacks are deposited in one run and in one step, by just changing the recipe.

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.

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.

In practice, this is basically centrotehrm many from the threat of any overseas trade restrictions and provides a safety net for the banks offering loans to the manufacturing segment. Excellent passivation characteristics Integrated surface conditioning good adhesion, no blistering Variable process sequences for multiple and pscvd layers High availability thanks to redundancy and short cycle times Up to 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.

As a result, PERC technology emerged as the next generation of industrial silicon solar cells. 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.

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.
