A New Thermoelectric Nanoantenna
May 21, 2019 | Leave a Comment
Collaborators of three labs in Mexico have demonstrated an innovative nanodevice for harvesting solar energy. The study paper has been published in the SPIE Journal of Nanophotonics. The paper, “Thermoelectric efficiency optimization of nanoantennas for solar energy harvesting,” reports that evolutive dipole nanoantennas (EDN) generate a thermoelectric voltage three times larger than the classic dipole […]

A Helmholtz-Zentrum Berlin für Materialien und Energie team has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation – making post-tempering at high temperatures unnecessary. The process makes it much easier to produce thin-film solar cells from this material. In comparison to metal-organic hybrid perovskites, inorganic perovskites are more thermally stable. The […]

New Material Hunt For Thermoelectric Generation
May 15, 2019 | Leave a Comment
University of Texas at Austin’s Texas Advanced Computing Center has shown that a voltage can be generated by harnessing differences in spin populations on a metal contact attached to a ferromagnetic material through a mechanism known as the Spin Hall effect. The researchers used supercomputers to identify various forms of cobalt oxide combined with nickel […]

Doubling Hydrogen Production Using Sunlight
May 14, 2019 | Leave a Comment
Princeton University engineer’s research has harnessed sunlight to isolate hydrogen from industrial wastewater, doubling the previous standard for splitting hydrogen from water in a scalable way. Hydrogen is a critical component in the manufacture of thousands of common products from plastic to fertilizers, but producing pure hydrogen is expensive and energy intensive. In a paper […]

Ecole Polytechnique Fédérale de Lausanne (EPFL) researchers have created a smart device capable of producing large amounts of clean hydrogen. By concentrating sunlight, their device uses a smaller amount of the rare, costly materials that are required to produce hydrogen, yet it still maintains a high solar-to-fuel efficiency. Their research has been taken to the […]
