Called Reflexite Soitec Optical Technology LLC., the new company will produce the silicone-on-glass (SOG) Fresnel lens plates used in Soitec’s concentrator photovoltaic (CPV) modules and co-develop next-generation technologies that will continue to increase the efficiencies and lower the costs of SOG lens plates. The joint venture will be located within the new CPV manufacturing facility that Soitec is planning to open in San Diego, California.

Reflexite will supply the technology and manufacturing expertise to produce injection-molded SOG lens plates at the “fab within a fab” to be built inside Soitec’s San Diego facility. Soitec is providing lens design expertise to achieve maximum performance across a wide range of operating conditions in CPV modules, business opportunities in the Southwest U.S., and the technical infrastructure of the factory. Soitec and Reflexite are currently collaborating on the design of the area of the factory to be dedicated to the Joint Venture, which will employ approximately 100 people.

One of the important elements in CPV systems is the lens plate, which incorporates a Soitec designed Fresnel lens that concentrates sunlight more than 500 times to achieve CPV technology’s industry-leading efficiency. Soitec was the first CPV company to use SOG to produce its lens plate design which combines the excellent durability of a glass surface with high-volume precision microreplication, the key to low-cost production.

Reflexite’s SOG lens plates claim to be the most durable on the market and provide excellent energy-generating efficiency, with no mechanical or chemical degradation such as yellowing, cracking and delamination. The combination of Soitec’s and Reflexite’s technologies provides the most durable, reliable, efficient CPV systems, generating consistent electricity output over the lifetime of a solar power plant.

Reflexite has been a long-time supplier of SOG lens plates to Soitec, and its optics are key elements in the CPV systems that have already won Soitec more than 300 MW in solar power plant projects throughout the Southwest USA.
