Whether during the crystallization of silicon, the sintering of contact layers, or PVD coating:
Any reaction between the material and the process environment can significantly impair the yield and quality of solar cells. A major challenge for the industry, solved by Henze BNP’s hexagonal boron nitride products!

Boron nitride is one of the most versatile materials in solar technology.
Its excellent temperature resistance, low wettability with respect to metals and silicon, and its electrical insulating properties make it an indispensable material in key process steps of solar cell manufacturing.

Typical applications:

• Silicon crystallization (Czochralski or pulling method)
• Sintering processes and diffusion steps
• PVD and CVD coatings in solar cell production
• Additives and release agents
