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.
