EMCORE Corp. (News - Alert) has achieved a record 39% conversion efficiency less than 1000x concentrated illumination in its multi-junction solar cell products that are being produced in high volumes. The solar cells have been designed for terrestrial Concentrator Photovoltaic (CPV) applications.
The EMCORE Concentrator Triple-Junction (CTJ) solar cells can operate in various conditions, which translates to 500-1000x concentration, for cost effective commercial CPV systems. The 39% record conversion efficiency of the cells was measured on 1-cm production concentrator solar cells and at 1000x illumination.
EMCORE presently manufactures ultra-high efficiency CTJ cells with a wide range of form factors. Over a million concentrator solar cells have already been shipped to CPV system manufacturers worldwide. Aiming to manufacture cells in high-volumes, EMCORE has continually invested in technological innovations to help develop concentrator solar cell products with conversion efficiencies of over 40% at high illumination operating conditions needed for state-of-the-art, economical CPV systems.
David Danzilio, vice president and general manager of EMCORE's Photovoltaics Division, said in a statement, "We believe this technical and operational advancement represents a significant value creation for our customers. Solar cells with 1000x conversion efficiency of 39% will enable CPV system developers to deploy competitive solar power installations with the lowest cost per kw-hr. We are committed to continuing our investment in CPV solar cell technology and production capacity to support our customers ever increasing requirements for performance, cost, and capacity."
