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 […]

3D Graphene is Solar Power’s Next Platinum?

Yun Hang Hu, the Charles and Carroll McArthur Professor of Materials Science and Engineering, has developed a new, inexpensive material that could replace the platinum in solar cells without degrading their efficiency: 3D graphene.

Graphene Solar Cells Now One Step Closer — Graphene Retains Its Unique Set of Properties

Graphene solar cells are now one step closer to reality, thanks to a new discovery made by researchers at the HZB Institute for Silicon Photovoltaics.
“We examined how graphene’s conductive properties change if it is incorporated into a stack of layers similar to a silicon based thin film solar cell and were surprised to find […]

Graphene paint could power homes of the future

Scientists at the University of Manchester used wafers of graphene, the discovery of which won researchers a Nobel Prize, with thin layers of other materials to produce solar powered surfaces. The resulting surfaces, which were paper thin and flexible, were able to absorb sunlight to produce electricity at a level that would rival existing […]
