Heterojunction Solar Cells

Vacuum Coating Equipment & Technologies

Heterojunction (HJT) solar cells combine the advantages of thin‑film and crystalline silicon technologies. Their exceptional electrical and optical properties, together with a streamlined process flow, enable manufacturers to achieve industry‑leading efficiencies in gigawatt‑scale production of bifacial cells.

We provide sputtering systems engineered for high‑throughput deposition of transparent conductive oxide (TCO) layers for HJT silicon solar cells. With more than 70 gigawatts of installed production capacity worldwide, our expertise ensures optimized processes, reliable field performance, and an outstanding price‑performance ratio.
