A revolution is already under way which includes development of autonomous wireless sensors, low-power consumer electronics, smart homes, domotics and the Internet of Things. All these elements require efficient and easy-to-integrate energy harvesting devices for their power. Billions of wireless sensors are expected to be installed in interior environments over the coming decades.
Graphene Flagship researchers at the University of Rome Tor Vergata, the Italian Institute of Technology (IIT) and its spin-off, Graphene Flagship Associate Member BeDimensional, in cooperation with Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) have successfully combined graphene with tandem perovskite-silicon solar cells to achieve efficiencies of up to 26.3%, which almost double the efficiency of pure silicon.
The development of next generation solar power technology that has potential to be used as a flexible ‘skin’ over hard surfaces has moved a step closer, thanks to a significant breakthrough at The University of Queensland (UQ) in Australia.
