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.

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 central innovations include modified ceramic and graphite spacers with included purge channels. 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.

However, according to Colville the move by Shaanxi Youser to expand capacity has other implications. Pre-requisite for a successful implementation is a highly efficient surface passivation of front and rear side.

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. 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.

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 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.

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

Centrotherm unveils new PECVD process for PERC solar cells

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

In practice, cetrotherm 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.

PECVD System Anti-Reflective Coating Passivation:

Advantages Time savings for regular maintenance work Reduced risk of damaging components Cuts down the number centrottherm 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.

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.

Solar Media Energy Storage News. Renewable Energy India Expo.

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. Aluminum Oxide AlOx with its excellent passivation properties and high negative fixed charge density is perfectly suited to achieve this.

It also highlights that new capacity from new entrants is still being based upon copying existing c-Si xentrotherm and multi process flows, and not moving to more exotic cell cetnrotherm.

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. The market analyst also referred to the increasing trade war impact on Chinese manufacturers and the response by the Chinese Government to rapidly develop its peccvd downstream PV market to support the entire domestic PV supply chain.

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