Biomolecular and Organic Electronics

We research on organic electronics, focusing on solar energy conversion, energy storage, and the interfaces between organic electronics and biosystems, ranging from biomacromolecules to cells and tissue.

Seeking Diploma Thesis Students!

We are currently seeking diploma thesis students to work on projects related to organic solar cells and modules. If you are interested in multi-disciplinary research on renewables, which requires intense collaboration with your colleagues, do not hesitate to apply or ask questions! The project will be designed according to your personal preferences, following a discussion with Prof. Olle Inganäs. Whether your are interested in physics, chemistry, engineering or software development we will do our best to accomodate your goals.

Contact person is Prof. Olle Inganäs


For the second year in a row Prof. Olle Inganäs and Prof. Fengling Zhang have been named Highly cited researchers and Highly Influential Scientific Minds in a ranking performed by Thomson Reuters. The ranking indicated 3000 top scientists in 21 different fields. Of 27 Highly cited researchers with affiliation in Sweden, only Zhang and Inganäs are active in Materials Science and the only two from Linköping University. Out of the 27 Swedish scientists listed only four were women of which Fengling Zhang was one.

We have published new materials useful for remediating water contaminated with metal ions, such as lead and arsenic. The material is based on the biopolymer lignin, and has been designed to allow electrochemical extraction of the metal ion, as well as electrochemical release. This electrode material is similar to those being developed for wooden batteries for storage of intermittent renewable electricity. We can thus combine water purification and charge storage in one material structure; using solar electricity to charge a wooden battery and removing metal ions from water in the same steps.


ERC Starting Grant
Feng Gao was awarded a prestigious ERC Starting Grant.

A new path towards highly efficient polymer solar cells
By collaborating with He Yan’s group at the Hong Kong University of Science and Technology and Kenan Gundogdu’s group at North Carolina State University, we demonstrated in Nature Energy that polymer solar cells can work efficiently with negligible driving force, proving a new path towards highly efficient devices.

Record efficiency for fullerene-free polymer solar cells
Published in Advanced Materials and highlighted by Nature. By collaborating with Jianhui Hou's group (CAS), we reported in a record efficiency (over 11%) for non-fullerene polymer solar cells, which also show excellent thermal stability.

Recent Work on Energy Storage
Our work on biopolymer based electrodes for wooden batteries and super capacitors is reviewed in Materials Horizons, focusing on the first generation of polypyrrole/lignin derivative hybrid materials. More recent work on PEDOT/lignin derivative, and on new polyaromatic quinone hybrids is published in Journals of Materials Chemistry A and Journal of Power Sources, forming the second and third generation of biopolymer based hybrid materials. Combinations of the second and third generation is found in the generation 4, just published in Advanced Materials Interfaces.
