CFC Composites for Solar

Technical Data – Key Points – CFC Sizes

CFC Composites for Solar production are ideal for manufacturers who are looking for an alternative to bulky and heavy graphite that can also aid the increase in  productivity while reducing their overall costs. The Neftec Corporation has been supporting the Photovoltaic industry for over a decade with their CFC Composites for solar.

Our CFC rods, Heat-Shields and Heater-plates offer exceptional durability, life-span and quality for Polysilicon production. PECVD CarrierNeftec also supplies parts for many other applications, this includes Crucible reinforcement parts, heat-shielding, molten silicon sealing components, along with our standard parts that include bolts and nuts, all these aid the production of Silicon Ingot production.

The manufacture of Solar cells have several stages of production that require highly technical materials to cope with the rigours of these manufacturing environments. C/C has always been a material that has been able to cope with these environments. Our CFC Composites for solar is not only extremely light, but it offers high strength, superior longevity, cost reductions.

Today you will find Neftec CFC Composites for solar are widely used in the production of silicon monocrystals and we offer a list of applications suited for silicon monocrystal production. These include; susceptors for CVD equipment and CFC Boats and carrier plates, these trays are light and well suited for the PECVD process during Solar Cell production.

Contact us today to find out how Neftec can help you and your Photovoltaic production needs.
