Project overview

Energy harvesting from renewable sources (solar, heat and movement) is a prominent solution to create small amounts of electrical energy in areas of difficult access, and energy harvesting devices have much potential to address our world energy problems. 

Nanowire (NW) based energy harvesting systems have achieved encouraging progress, but due to nanometre (nm) dimensions of the wires and large size (square meter) of the devices, they also bring challenges for testing and characterisation.

17 Nanotechnology Laboratories

Support Europe's Future Demands for Renewable Energy

This project aims to develop reliable and high throughput metrology for the quality control of NW energy harvesting systems. Read more
