GOVT/EXTERNAL FUNDING SOURCES

Government Funding/Support to Date: Beet’s innovation originates from targeted research on new absorber materials funded via the Center of Inverse Design, an Energy Frontier Research Center, DOE, Office of Basic Energy Science. Best-of-class materials, selected from hundreds of candidates, exhibit physical properties that outperform existing absorber materials on the market. The material’s family selected for PV integration by Beet Inc. can bring a disruptive high-efficiency solution to the market. The ongoing development is focused on moving the design-based materials to unconcentrated solar cells with efficiencies exceeding 30%.
2014: Oregon State University Venture Development Fund (6 mo.) supports early prototype development.
