Milestones in the history of the Section for Organic Energy Materials

2015: Completion of 'Solar 100'

In this project an exhaustive work has been done screening over 100 polymers in search of the best performing candidates for processing polymer solar cells in large scale.

2013: Launch of free OPV samples for research and education.       

 Free OPV

2013: Launch of Coursera course on Solar Cells


is an education company that partners with universities and organizations all over the world to offer courses online for anyone to take, for free. DTU Energy Conversion and Storage is taking part in this partnership, and we are proud to be able to offer a Coursera course on organic solar cells.

Our new Coursera course focuses on organic solar cells, a 3rd generation solar cell technology, which can be produced in very large scale. The main areas of the course are: Solar energy, solar cells in general, organic solar cells and the materials, stability and production of these.


2012: Installation of Solar Park at DTU

Solar Park

A pilot project investigating DTU’s concept for large-scale polymer solar cell installations is initiated.

A 1000 m2 test site is erected at DTU Risø Campus at Technical University of Denmark’s Department of Energy Conversion and Storage.


2010: Industrial production of polymer solar cells

The Danish manufacturing company Mekoprint, whose core technology is printed electronics, sets up a production line for polymer solar cells.

Our focus now turns 100% on developing polymer solar cells for large-scale electricity production.

2009: First grid-connected polymer solar cells in the world.


Solar cells are connected to the Danish electricity grid for the first time. Three panels, each capable of producing 7 W, are connected to the electricity grid to demonstrate that it is possible.


2009: Solar-powered reading lamp for African schoolchildren  

Lightening Africa

Polymer solar cells are applied in reading lamps, which are then distributed among schoolchildren in Zambia. The lamps are based on a rechargeable battery and a LED light source. The idea is to provide an affordable alternative to the polluting and unhealthy kerosene lamps that are widely used in developing countries.


2008: First public demonstration of functioning polymer solar cells: “The Solar Hat”.

Solar Hat

Polymer solar cells are applied in 200 hats, which are distributed at the Roskilde Festival. The cells charge a small FM radio, so guests can listen to music.

2008: We install the first roll-to-roll manufacturing machine for polymer solar cells at DTU.

Solar Coater

2001: Frederik C. Krebs (now Professor in Section for Organic Energy Materials) receives a grant from the Danish Council for Technology and Innovation (STVF, talent programme) for his work with poymers. This gives him the opportunity to head start his research career within polymer solar cells.
