Heraeus Photovoltaics Launches Innovative Infrared Emitters for Optimized Diffusion

Heraeus Infrared Emitters are entirely made out of quartz glass, which has an unmatched purity to avoid contamination and allows the transfer of large amounts of energy in a contact free manner.

Heraeus Photovoltaics is now offering innovative Infrared Emitters (IR-emitters) for optimized diffusion, Anti-Reflective Coating and drying processes in silicon solar cell production. IR-emitters react instantly and are therefore easy to control and regulate.

The IR-emitters are entirely made out of quartz glass, which has an unmatched purity to avoid contamination and allows the transfer of large amounts of energy in a contact free manner. Its outstanding stable temperature resistance enables applications under vacuum and ensures a particularly consistent process and increases the overall energy efficiency of the production process. As the reflector is coated with nano opaque (white) quartz glass (QRC), the IR-emitters allows for a very compact design and thus requires very little working space. Quartz glass is also resistant to acids, lyes and other aggressive substances.

Heraeus IR-emitter solutions are tailor-made for the short and medium IR-wavelengths required in different process steps of the solar cell production. Due to their high reliability and consistency of heating process an increased production yield is possible. Furthermore, the instant heat emission allows the homogenous heating of solar cell wafers with very fast response times of 1-2 seconds. The high quality of the IR-emitters also ensures increased uptimes.

“Heraeus Photovoltaics holds an unrivaled technological and process knowledge in the Photovoltaic Industry. We apply this to develop much stronger into a provider of comprehensive technology and service solutions for our customers. We are convinced that by increasing efficiencies throughout the whole value chain the costs of renewable energies can be reduced by a further 50 percent within the next five years. Heraeus and its experts will be able to contribute about one-third to this cost reduction,” said Andreas Liebheit, President Heraeus Photovoltaics.

Heraeus exhibits its full range of products and services at the 11th SNEC International Photovoltaic Power Generation Conference & Exhibition 2017 in Shanghai. Customers will be able to meet the Heraeus Noblelight experts at the Heraeus stand during the exhibition.
