DOE Awards Ascent Solar TCF Grants for Two Solar Projects

Ascent Solar Technologies, Inc. a developer of flexible CIGs thin-film photovoltaic (PV) solutions based in Thornton, Colorado, reported that U.S. Department of Energy (DOE), supported by the Office of Technology Transitions (OTT) Technology Commercialization Fund (TCF) selected the company for two exclusive development projects.

TCF funds require a 50 percent match of non-federal funds from private partners. The full list of TCF selections and the private sector partners can be found at:

For the two awards, worth up to $100,000 each, Ascent Solar will work towards commercializing the sputtered Zn(O,S) buffers in flexible CIGS solar cells and also seek to develop of next-generation, high-efficiency Perovskite/CIGS Tandems cell.

The first project will employ sputtered Zn(O,S) buffers, which is expected to help reduce costs and further improve the environmental friendliness of the company’s CIGS fabrication process. The second project, which intends to develop high efficiency, tandem Perovskite/CIGS solar technology, is expected to enhance efficiencies and reduce costs with a more complete conversion of the solar spectral energy into electricity.

U.S. Secretary of Energy Rick Perry commented, “The projects announced today will further strengthen those efforts across a broad spectrum of energy technologies and advance DOE’s important mission of technology transfer.”

Dr. Lawrence Woods, director and head of research & development for Ascent Solar commented, “While there are challenges to be overcome with the use of perovskite-based devices, with already proven high-efficiencies, we believe that Ascent Solar is well positioned to incorporate these materials into our large-scale roll-to-roll processing.”

Dr. Joseph Armstrong, CTO and founding member of Ascent Solar Ascent Solar says of the two projects, “In both cases, we are leveraging our significant intellectual property with flexible monolithically integrated CIGS and teaming with the National Renewable Energy Laboratory (NREL) to inject their substantial knowledge in novel advanced materials to create a potentially substantial leap in the advancement of our product.”
