NREL Achieves World Record in PV Cell Efficiency

Scientists at the National Renewable Energy Laboratory (NREL) in Golden, Colorado, have achieved a new world record in thin-film photovoltaic cell efficiency. A record 17.7% “sunlight-to-electricity” efficiency was achieved with a compound semiconductor called copper indium gallium diselenide. While this efficiency is 60% higher than the equivalent efficiency of amorphous silicon thin-film PV cells, NREL expects that this technology is 10 to 15 years away from commercialization.
