U.S. pledges to slash solar energy costs by 60% in a decade

• $40 million for perovskite R&D: Perovskites are a family of emerging solar materials that have potential to make highly efficient thin-film solar cells with very low production costs. DOE is awarding $40 million to 22 projects that will advance perovskite PV device and manufacturing research and development—as well as performance through the formation of a new $14 million testing center to provide neutral, independent validation of the performance of new perovskite devices.
• $3 million Perovskite Startup Prize: This new prize competition will speed entrepreneurs’ path to commercializing perovskite technologies by providing seed capital for their newly formed companies.
• $20 million for CdTe thin films: The National Renewable Energy Laboratory will set up a consortium to advance cheaper CdTe thin-film solar technologies, which were developed in the United States and make up 20% of the modules installed in this country. This consortium will advance low-cost manufacturing techniques and domestic research capabilities, increasing opportunities for U.S. workers and entrepreneurs to capture a larger portion of the $60 billion global solar manufacturing sector.

• $33 million for CSP advances: The new funding opportunity also includes funding for improvements to the reliability and performance of CSP plants, which can dispatch solar energy whenever it is needed; identifies new solar applications for industrial processes, which contribute 20% of U.S. carbon dioxide emissions; and advances long-duration thermal-energy storage devices. Long-duration energy storage is critical to decarbonizing the electricity sector and couples well with CSP plants, but the cost must fall by a factor of two to unlock deployment.
• $25 million to demonstrate a next-generation CSP power plant: Sandia National Laboratories will receive funding to build a facility where researchers, developers, and manufacturers can test next-generation CSP components and systems and advance toward DOE’s 2030 cost target of 5 cents/kWh for CSP plants.
