SunFlake is developing a new generation of solar cells based on
a novel shape of semiconductor nanostructures (NanoFlakes).
The patent pending nanostructures can eliminate the need for a
lattice-matched substrate as well as the need for a clean solar
grade substrate.
The only purposes for the carrier substrate are to allow for the
growth of the nanostructures and - when the solar cell is
operating - act as a contact to the light absorbing nanostructures. |

A few of the potential advantages of the SunFlake solar cell design:
• n-p junctions in perfect single crystals on a non-lattice
matched substrate.
• Short distance from electron-hole pair generation to
the n-p junction.
• Only small amounts of expensive solar grade material is
used in the nanostructures, none in the substrate. |
