SunFlake combines III-V semiconducting nanotechnology with
standard silicon solar cells in a disruptive tandem solar cell with
material costs similar to that of crystalline silicon solar cells, but
with 50% higher conversion efficiency. World record efficiency on
individual nanowires is already achieved.
The nanostructures provide an ideal light trapping geometry.
Less than 5% areal nanowire coverage absorbs more than 96%
of incoming light, making a nanowire covered surface one of the
darkest materials in the world. |

SunFlake solar cells are hence ideally suited for energy harvesting
The essential parameters:
• High power output per area/weight
• High tolerance towards the incidence angle
• Low sensitivity towards the spectral changes
– all lie intrinsically in the SunFlake technology |
