SunFlake develops NanoFlakes
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.
