SunFlake is a science spinout company from Nano-Science Center at Copenhagen University.

Focal point of the newly established company is the development of an exceptional effective solar cell, based on new shapes of semiconductor nanostructures.

The patent pended nanostructures used by SunFlake enables a diminished need for complicated time consuming and expensive processing steps.

A large surface to volume ratio of the developed nanostructures as well as the texture of the covered surface allows a high absorption coefficient of the incoming sunlight without the use of an antireflective layer.

Control of nanostructures allows SunFlake to combine different semiconductor materials since requirements such as the need for a similar crystal structure as the carrier substrate is relaxed. 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.

This circumstance will influence the cost of the final solar cell dramatically since only minute amounts of expensive ultra clean material is needed, compared to state of the art classically silicon solar cells today.

SunFlake is among the very first companies to use nanostructures as the only active element in a solar cell. The prospect of achieving record high conversion efficiencies combined with a reduction in fabrication cost give SunFlake a strategic advantage on the fast growing competitive photovoltaic market.

Copenhagen University (KU) and SEED Capital initially funded SunFlake in first Quarter of 2007.
