WP5 – Process and Device Development

WP5  is aimed at fabricating enhanced efficiency thin-film solar cells, leveraging on light-trapping enhancement of quantum dots harvesting and photon recycling.  The main objectives are:

  • demonstration of fully processed photon-recycling enhanced thin-film cell on foreign carrier with optimized rear reflector;
  • demonstration of fully processed light-trapping enhanced nanostructured thin-film QD solar cell.
