The SunShot Foundational Program to Advance Cell Efficiency (F-PACE) aims to increase the efficiency of photovoltaic (PV) cells achieved in the laboratory and on manufacturing lines.
Launched in September 2011, the first round of the F-PACE program supported 18 research projects over a 36-month performance period. These efforts laid the technical foundation for significant increases in PV efficiency by identifying cost and efficiency barriers and researching PV sub-cell materials and processes.
Through the second round of this program, announced in 2013, four collaborative research teams are working to define and fabricate model systems that can approach theoretical power conversion efficiency limits for a chosen bandgap and absorber material.
F-PACE II Awardees
