Did you know that crystals form the basis for the penetrating icy blue glare of car headlights and could be fundamental to the future in solar energy technology?
Solar power cells are limited by the wavelengths of light they can absorb from the sun. Ideally a solar cell would absorb every wavelength, but to date the goal has not been reached. Silicon, today's photovoltaic industry standard, is limited in the wavelength range it can 'see' and absorb.
PHOENIX, July 11, 2011/PRNewswire/ -- RoseStreet Labs, (RSL), announced today the world's first demonstration of a long wavelength LED device utilizing low cost silicon wafer substrates.
Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps).
