By combining designer quantum dot light-emitters with spectrally matched photonic mirrors, a team of scientists with the Lawrence Berkeley National Laboratory and the University of Illinois “achieved a luminescent concentration ratio greater than 30 with an optical efficiency of 82% for blue photons,” the highest luminescent concentration factor ever recorded. This breakthrough paves the way for the future development of low-cost solar cells that efficiently utilize the high-energy part of the solar spectrum.
The solar energy industry in the United States is soaring with the number of photovoltaic instal...
