Ascent Solar Technologies, a manufacturer of flexible thin-film photovoltaic (PV) solutions, has been selected by the US Department of Energy (DOE), supported by the Office of Technology Transitions (OTT) Technology Commercialization Fund (TCF), for two exclusive development projects.

As part of the awards, worth up to $100,000 each, Ascent Solar is to work towards commercialization of sputtered Zn(O,S) buffers in flexible CIGS solar cells and also development of next-generation, high-efficiency Perovskite/CIGS tandem cell. These projects are part of Ascent Solar’s plans for next-generation lightweight and flexible solar cells.

The first project will use sputtered Zn(O,S) buffers, which will help reduce costs and would further improve the environmental friendliness of our CIGS manufacturing process. The Perovskite/CIGS tandem junction project is designed to significantly improve efficiencies and drive further cost reduction by enabling a more complete conversion of the solar spectral energy into electricity.

“These are challenging yet exciting projects," says Lawrence Woods, Director and Head of Research & Development for Ascent Solar. “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."
