Heterojunction Solar Cells

Vacuum Coating Equipment & Technologies

Heterojunction solar cells (HJT) unite the strengths of thin‑film and crystalline silicon technologies. Their outstanding electrical and optical properties, combined with a streamlined process flow, enable our customers to achieve top‑tier efficiencies in gigawatt‑scale production of bifacial solar cells.

We supply sputtering systems designed for high‑volume manufacturing of transparent conductive oxide (TCO) layers for HJT cells. With more than 70 gigawatts of installed production capacity worldwide, our experience translates into optimized processes, proven reliability, and an exceptional price‑performance ratio.
