A new technique using a radical polymer and functionalized fullerene derivative improves the stability and power conversion efficiency of perovskite solar cells, paving the way for larger-scale use in solar energy.
Scientists underscore the potential of a new class of materials to convert sunlight to fuel.
A team of researchers highlights in an article published in Coordination Chemistry Reviews the potential of covalent organic frameworks (COFs), a new class of light-absorbing materials, in solar-to-fuel production.
A team of researchers at Germany-based Fraunhofer Institute for Solar Energy Systems ISE reported having achieved a record conversion efficiency of 26.0 per cent for both-sides contacted silicon solar cells.
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.
Solar energy harvested in space offers the potential for an unlimited and constant zero carbon power source.
The UK government has commissioned new research into space-based solar power (SBSP) systems that would use very large solar power satellites to collect solar energy, convert it into high-frequency radio waves, and safely beam it back to ground-based receivers connected to the electrical power grid.
The Fraunhofer Institute for Solar Energy Systems ISE has reported a new record efficiency of 25.9 percent for a III-V/Si tandem solar cell grown directly on silicon. This cell was produced on a low-cost silicon substrate for the first time – marking an important milestone on the way to economical solutions for tandem photovoltaics.
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.
