Winner R&D 100 Award, and Most Promising New Technology
“Multi-Band” Solar Cell Technology Wins R&D 100 Award and is Licensed for Commercial Applications
Wladeslaw Walukiewicz and Kin Man Yu

The LBNL multiband technology (see highlight 04-1, ) has been named a 2006 R&D 100 Award winner. It was selected by R&D Magazine as one of the most “significant proven technological advances of the year.” Confirming this potential, RoseStreet Labs has obtained an exclusive license the technology from LBNL. This license complements and expands the Phoenix based company’s existing exclusive license for full spectrum solar cells utilizing unique multijunction technology developed jointly by LBNL and Cornell University. RoseStreet Labs believes that Berkeley Lab's technology can potentially achieve efficiencies above 48% in a single junction device and represents a technical breakthrough that may significantly reduce the complexity and manufacturing costs associated with high solar efficiencies.

 

 

 

 

 



Rose Street Labs is a supplier of products and services for wireless infrastructure in the renewable energy, homeland security markets and life sciences. It believes that the LBNL technology represents a breakthrough in multi-band semiconductor materials and that it will lead to leapfrog advances in solar cell applications, such as high-efficiency products for a broad range of renewable energy applications—at a cost close to prevailing conventional silicon based cells, but with significantly higher efficiencies.
