BURGHAUSEN, Germany—Wacker Chemie A.G. has named a project team at the supplier's polysilicon production site in Burghausen as the winner of this year's Alexander Wacker Innovation Award.
The team, comprising Paul Bonisch, Markus Wenzeis and others, was awarded for making innovative improvements to the efficiency of the polysilicon manufacturing process.
Polysilicon is used in semiconductors and solar arrays, as well as aluminum and silicone rubbers, in different grades.
"With this pioneering approach, we are strengthening our position as technology and market leader in the production of ultrapure polysilicon," Wacker Executive Board member Angela Worl said in a statement. "At the same time, the new process makes an important contribution to achieving our CO2 reduction targets."
Bonisch, Wenzeis and team were able to change the control system in polysilicon manufacturing in such a way that its deposition can be controlled in real time with a sensor-based approach. Essentially, this means that adjustments to the reactor conditions are now possible as the reactor operates.
"The efficiency of the entire process can be improved, and the quality of the end product further stabilized," Wacker said in a release announcing the award. "The production process also becomes considerably more sustainable."
