QuantaSol unveils 28.3 per cent efficient single-junction solar cell

QuantaSol, an independent designer and manufacturer of strain-balanced quantum-well solar cells, has developed what it believes to be the most efficient single junction solar cell ever manufactured. Developed in the last two years, QuantaSol's single-junction device has been independently tested by Fraunhofer ISE as achieving 28.3 per cent efficiency at greater than 500 suns.
