IBC solar cells

The most advanced PV modules on the market today rely on interdigitated back contact (IBC) solar cells. As the name suggests, all electrodes are placed on the rear side of the cell. Relocating…

Heterojunction solar cells

Heterojunction (HJT) solar cells unite the strengths of thin‑film and crystalline silicon technologies. Their outstanding electrical and optical properties, combined with an efficient process flow,…

Large-Area Optics

If you require coating solutions for large optical surfaces with extremely demanding specifications—such as those used in astronomical reflecting telescopes—our magnetron sputtering technology…

Building-integrated Photovoltaics

Integrated photovoltaics allow the building envelope to serve two purposes at once: protecting the structure and generating electricity. At the same time, architects must retain full creative…

Windows & Facades

Manufacturers and coaters of architectural glass operate at the limits of what is technically feasible, all while balancing cost, quality, and delivery performance. Our glass coating systems…

Lithium-Ion Batteries

Lithium‑ion batteries underpin modern electromobility thanks to their high energy and power density. As demand grows for longer driving ranges and shorter charging times, the pressure to enhance…

Micro-electro-mechanical systems

Micro‑electro‑mechanical systems (MEMS) are miniature devices that integrate mechanical structures with electronic functionality. They are essential components in a broad range of applications,…

Optical Interference Filters

Optical interference filters—such as bandpass, dichroic, polarizing, notch filters, and beam splitters—must meet demanding requirements: minimal optical losses, ideally no absorption or scattering,…

Optical Windows

Optical windows transmit light within defined wavelength ranges while shielding opto‑electronic systems from environmental influences. Their dimensions and geometries can vary widely, though they…
