Solar Media Energy Storage News.

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. Sign In Sign Up. Given that the deposition is limited to the wafers and graphite boats, the centrottherm tubes are only marginally impacted by parasite coating and have to be cleaned fairly once a year.

Here is a preview. Sign Up Sign In. We send out a daily email newsletter with the latest in depth news and analysis. The 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. The centfotherm analyst also referred to the increasing trade war impact on Chinese manufacturers and the response by the Chinese Government to centrorherm develop its domestic downstream PV market to support the entire domestic PV supply chain.

Centrotherm also received orders for its annealing systems for a MW monocrystalline solar cell production line. Pre-requisite for a successful implementation is a highly efficient surface passivation of front and rear side.


As a result, PERC technology emerged as the next generation of industrial silicon solar cells. Aluminum Oxide AlOx with its excellent passivation properties and high negative fixed charge density is perfectly suited to achieve this.

Renewable Energy India Expo. The stack is compatible with standard Al pastes and shows a high passivation quality after contact firing.

Moreover, yield declines and the risk of damages to the boats as a result of improper handling are also minimized. Finlay Colville, vice president of NPD Solarbuzz told PV Tech that the expansion plans from Shaanxi Youser went back several years, with key cengrotherm suppliers having waited for some time to get the first orders.

This dispenses with periodic reactor cleaning and increases equipment availability. We send out a daily email newsletter with the latest in depth news and analysis.

Availability Upgrade solution ready for shipment with short delivery times. I would like to receive information from carefully selected 3rd parties that may have products and services of interest to me. 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.

Renewable Energy India Expo. 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.

Production Equipment

The central innovations include modified ceramic and graphite spacers with included purge channels. 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 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 pecdv start-up as well as the integration into existing production lines.


By adding this hardware kit, all centrotherm PECVD systems can easily be upgraded with minimum space requirements. 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 centrohterm.

Furthermore, these stacks are deposited in one run and in one step, by just changing the recipe.

However, according to Colville the move by Shaanxi Youser to expand capacity has other implications. Subscribe me to PV-Tech Newsletter. 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 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 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. Subscribe me to PV-Tech Newsletter.
