Graphene battery demonstrated to power an LED

Scientists in Hong Kong have reported, in ArXiv, their experiments to make a graphene battery that they say generates an electrical current by drawing on the ambient thermal energy in the solution in which it is immersed.

Graphene creates electricity when struck by light

Graphene could be used as a highly-sensitive photodetector that works across a huge swath of the spectrum, including infrared which many sensors struggle with. The same tech could be applied to night-vision goggles for military useThe discovery was made by a team of researchers from MIT in the US and the National Institute for […]

Best of Both Worlds Power Storage from GrapheneSupercapacitors

Graphenesupercapacitors have immense potential to revolutionize the efficiency and environmental-friendliness of our electronics. Especially after the researchers discuss about graphene’s potential, it’s difficult not to be excited for the future of this technology.

Graphene ‘multiplies’ power of light

Graphene can convert a single absorbed photon into “multiple” electrons that can drive electric current – which the ICFO, Barcelona-led research team describe as “a very promising discovery” that makes graphene an important alternative material for light harvesting technologies, now based on conventional semiconductors like silicon.

World’s thinnest substance graphene ‘will power the next generation of computers’

The researchers found that electrons travel a lot more quickly in graphene than they do in silicon; the substance current computer chips are made out of. A new generation of computers and smartphones could run much faster if they were made from the world’s thinnest substance, scientists have claimed.

Proof: graphene can convert sunlight to electricity

Graphene has an excellent ability to convert solar radiation into energy.Researchers found that Graphene contains the basis for a mechanism known as carrier multiplication. This mechanism involves the generation of multiple electron-hole pairs from the absorption of a single photon.

Researchers advance scheme to design seamless integrated circuits etched on graphene

Researchers in electrical and computer engineering at University of California, Santa Barbara have introduced and modeled an integrated circuit design scheme in which transistors and interconnects are monolithically patterned seamlessly on a sheet of graphene, a 2-dimensional plane of carbon atoms. The demonstration offers possibilities for ultra-energy-efficient, flexible, and transparent electronics.

Graphene-Coated Silicon Power Cell Signals a Battery-Free Future

Traditional batteries which store energy in chemical reactions, a new device stores electricity by assembling ions on the surface & the engineers coated the surface with graphene. A team of engineers at Vanderbilt just built such a device. The Graphene protect the silicon; it also improved the device’s energy density by over two orders […]
