Frequently Asked Questions
Why is boron nitride needed in the manufacture of solar modules?
Heating elements made of graphite or copper are used in the production of silicon wafers, which form the core of modern solar modules. These sensitive components are exposed to extreme thermal loads during the production process and must be protected by reliable electrically insulating ceramics. Boron nitride is the ideal material for this, as it has precisely these protective properties.
Which Henze BNP products are used in the photovoltaic sector?
For demanding insulation applications in solar and semiconductor technology, we manufacture precision components from our sintered HeBoSint® materials. These serve as essential protective components and insulators for sensitive heating elements, thereby ensuring a safe and trouble-free manufacturing process.
What properties make HeBoSint® the best solution for wafer production?
Photovoltaics require excellent thermal management combined with outstanding electrical insulation. HeBoSint® components combine precisely these seemingly contradictory properties: they provide excellent electrical insulation and withstand the enormous temperatures during silicon wafer production over the long term, making them often the best and safest solution for this application.
