MANHASSET, N.Y. RoseStreet Labs has signed a license agreement with Lawrence Berkeley National Laboratory
(Berkeley Lab) to commercialize multi-band semiconductors and high-efficiency solar cells.
This agreement will support RoseStreet Labs' (Phoenix) commercialization of full spectrum photovoltaics for terrestrial, distributed energy, military and space applications. RoseStreet Labs expects to spin out its solar operations by year-end into an entity named RSL Energy.
RoseStreet Labs believes that Berkeley Lab's (Berkeley, Calif.) technology can potentially achieve efficiencies above 48 percent in a single junction device. The technology encompasses a breakthrough multi-band material that may reduce the complexity and manufacturing costs associated with high solar efficiencies.
RSL Energy will commercialize Berkeley Lab's technology at its Phoenix R&D Laboratory and introduce an Intermediate Band Solar Cell product series (IBSC) with the technology. This license complements and expands RoseStreet Labs' existing exclusive license for full spectrum solar cells utilizing unique multijunction technology announced April 19, 2005 with both Berkeley Lab and Cornell University.
RSL Energy will leverage RoseStreet Labs' Phoenix-based R&D Laboratory and its high volume foundry, FlipChip International, to produce a competitive market entry for full spectrum solar cells into the global renewable energy market.
