Organic Energy Harvesters

Organic energy harvester

Organic materials display various electronic structures, morphologies, polarizations, transport properties that can be tuned through molecular design via organic synthesis. Some of those properties enable new pathways to convert mechanical, thermal or chemical energy into electricity.

Replacing bulky energy converters with thin smart organic materials

Within the research area of organic energy harversters, we use organic and 2D based hybrid/composite materials to fabricate thermoelectric, thermogalvanic, piezoelectric and pyroelectric generators and sensors.

One of the feature of organic materials is the ability to process them from solution, such that new energy devices can be produced by additive manufacturing techniques such as printing techniques, electrospinning, ….

Our vision is to create the next generation of green, cheap, reliable energy devices for the coming revolution of internet of everything. The emphasis is to combine energy conversion and mechanical compatibility for flexible and wearable electronics. 

Some of our long-term research interests are also in the use of forest materials for thermal management including heat conduction and thermal insulation; as well as active or passive cooling and heating effects.
