Researchers have established a new world efficiency record for quantum dot solar cells, at 13.4 percent.
The race to achieve ever-higher photovoltaic conversion ratios is, so to speak, a hot area of research. One line of research has focused on quantum dots – semiconductor nanocrystals under 2-10 nanometers (about 10-50 atoms) in diameter in which electron motion is confined in all three dimensions – as the fundamental elements of nanoscale solar cell technology.
