Future solar cells may be made of wood

(Phys.org) —A new kind of paper that is made of wood fibers yet is 96% transparent could be a revolutionary material for next-generation solar cells. Coming from plants, the paper is inexpensive and more environmentally ...

Transparent metal films for smart phone, tablet and TV displays

A new material that is both highly transparent and electrically conductive could make large screen displays, smart windows and even touch screens and solar cells more affordable and efficient, according to the Penn State ...

Researchers use sound to slow down, speed up, and block light

How do you make an optical fiber transmit light only one way? Researchers from the University of Illinois at Urbana-Champaign have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced ...

Physicists scale up invisibility cloaks using natural crystals

(PhysOrg.com) -- Physicists from the University of Birmingham, with colleagues at Imperial College, London, and Technical University of Denmark, have demonstrated an 'invisibility cloak' that can hide a three-dimensional ...

Nanometer Graphene Makes Novel OLEDs Display

Researchers at Stanford University have successfully developed brand new concept of organic lighting-emitting diodes (OLEDs) with a few nanometer of graphene as transparent conductor. This paved the way for inexpensive mass ...

Graphene layer enables advance in super-resolution microscopy

Researchers at the University of Göttingen have developed a new method that takes advantage of the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows ...

Dense yet transparent materials offer new way to control light

Researchers recently made the surprising discovery that a special class of materials called "hyperuniform materials" can be both dense and transparent. This work demonstrates a new way to control light and could lead to novel ...

Silicon-based metamaterials could bring photonic circuits

New transparent metamaterials under development could make possible computer chips and interconnecting circuits that use light instead of electrons to process and transmit data, representing a potential leap in performance.
