The Photovoltaic Materials and Systems group


Our projects

The group Photovoltaic Materials and Systems at DTU Fotonik performs scientific research and development on optical sensors, micro- and nanostructured materials for sensing purposes and production of micrometer-nanometer thin films with pulsed laser deposition (PLD) and wet-chemistry methods.

Latest News

April 2016: We achieved a new world record for a PLD CZTS solar cell with an efficiency of 5.2%. This device was made up from a CZTS thin film fabricated at DTU by PLD, and the cell was completed in collaboration with University of New South Wales (UNSW) in Sydney.

December 2013: PhD student Swathi Murthy joined the group with Henrik Chresten Pedersen as supervisor. Her project is called "Large area coloring using aluminum nanostructures".
