Energy

High-purity starting materials are the basis for efficient and durable energy technologies. Our synthesis and purification processes deliver ultra-clean materials such as graphite and SiC powder, tailored for semiconductor, fuel cell, and power electronics applications.

Precise crystal growth maximizes performance in solar and power systems. Our systems produce high-quality crystals — including silicon ingots, SiC boules, AlN, Ge, and InP — with the electrical, thermal, and optical properties needed for high-efficiency devices.

Silicon for solar applications is produced in large-scale fluidized bed systems continuously fed with silicon sand. The FBR process is also used to coat graphite-based powders for high-performance battery anodes or to produce carbon nanotubes for advanced materials.

Our plasma technology creates functional surfaces and ceramic protective coatings that protect critical energy components — such as vacuum interrupters — from corrosion, abrasion, and thermal stress. This extends service life and reliability in power generation and distribution.

Quality and reliability start with precise inspection. Our non-destructive testing solutions — including SAM and SIRD — detect microcracks, stresses, inclusions, and defects early in production, ensuring consistency and durability under demanding conditions.

PVA's Hyperspectral Vision technology offers a fast, contactless, and comprehensive inspection of the anti-corrosion layer on bipolar plates. It provides spatially-resolved data on layer thickness, homogeneity, and defects across the entire bipolar plate.
