SEMCO Technologies is a pioneer in reduced pressure processing applied to photovoltaic solar cell mass-manufacturing and owns all the main patents related to this technology.

The company started offering the current standards years ago at a time when high-efficiency PV and mass-production were still abstractions. By applying proprietary principles worked out and validated by the company in the semiconductor industry, SEMCO Technologies paved the way for today's requirements of cell manufacturers in the PV market. Thus, SEMCO Technologies is continuously innovating to meet customer demand, focusing on improvement in Phosphorus & Boron emitter diffusion, thermal SiOx & AlOx growth and SiNx deposition. Our business unit, SEMCO Technologies PVE delivers cost-effective solutions that increase solar cell performance, optimize line throughput and lower operating expenses.
