U.S. Department of Energy Secretary Steven Chu last week announced that the Department of Energy's National Renewable Energy Laboratory (NREL) will invest US $12 million in total funding ($10 million from the American Recovery and Reinvestment Act) to support the development of early stage solar energy technologies.

The anticipated subcontracts, up to $3 million each, will be awarded as 18-month phased subcontracts with payment made on completion of project milestones.
