Researchers demonstrate a new method to fabricate solar perovskite solar cells in ambient air bringing their efficiency up to 18.3%, which could boost perovskite technology towards production and commercialization of high performance and stable devices.
Stanford scientists invent an ultrafast manufacturing process to produce stable perovskite cells and assemble them into solar modules that could power devices, buildings and even the electricity grid, according to the study Rapid Open-Air Fabrication of Perovskite Solar Modules published by the research team in the Nov. 25 issue of the journal Joule.
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.
