Singulus Technologies has successfully tested the new processing facilities for the production of high-performance modules at Russian firm, Hevel Solar. The German company delivered the machines from the type SILEX II to the PV manufacturer at the end of last year, Singulus said on Wednesday.
The new facilities allow Hevel to finally convert its production line from silicon thin-film to heterojunction modules. In addition to the SILEX II production systems for the wet-chemical processing of heterojunction solar cells, Singulus also delivered a range of chemical supply units and facility infrastructure for the production of heterojunction solar cells. This offers the Russian company a capacity in excess of 5,000 wafers per hour.
According to Singulus, the supplied SILEX II is a system that transports four carriers with solar cells in parallel and uses various processing baths with ozone-based cleaning steps, which have short process times, and a low usage of chemicals. Singulus says that this processing steps plays an important role in improving solar cell efficiency and reducing production costs.
In this context, in February Hevel Solar announced that it has reached 21.75% cell efficiency for its heterojunction solar cells. After the upgrade of its cell and module manufacturing facility in Novocheboksarsk in Russia, the company plans to produce 160 MW of solar modules annually.
Hevel says that the “main part” of the output from the HJT line will primarily be used for its own projects. The company claims that it has projects totalling 364 MW in the pipeline.
