These projects are intended to develop innovative, early-stage solar power technologies to reduce the cost of solar energy to $0.03 per kilowatt hour by 2030.
“The SunShot Initiative is a proven driver of solar energy innovation,” said director Charlie Gay. “These projects ensure there’s a pipeline of knowledge, human resources, transformative technology solutions, and research to support the industry.”
The projects cover modules and systems in Photovoltaics Research and Development (PVRD2) and Technology to Market 3 (T2M3), which supports early-stage solar technology research.
Over $20m will be spent on 28 projects in RVRD2. These include a Low-Cost Scaffold-Reinforced Perovskite Solar Module with Integrated Light Management and Perovskite on Silicon Tandem Solar Cells at Stanford University as well as a new cell interconnection technology that could improve module efficiency by Stion California. The University of Utah is investigating Spread Spectrum Time Domain Reflectivity for String Monitoring in PV Power Plants, while Fraunhofer USA’s Centre for Sustainable Energy Systems is looking at ways to stick conventional PV modules to residential roofs.
The T2M3 projects will share $25m, including a molten salt energy storage for solar concentrators by SolarReserve, a magnesium carbonate energy storage system from EchoGen Systems, a new gallium nitride inverter architecture by Power Integration Laboratory and a cloud-based utility-scale energy management architecture from KrytonCloud.
