Better together: Perovskites paired with silicon could create higher-efficiency solar cells

By Stephanie Liverani / January 19, 2016

Researchers at the University of Oxford in England say perovskites are the class of materials that will change the solar cell game not by themselves, but when teamed up with our reliable standby material, silicon.

New projects worth millions announced on Materials Genome Initiative second anniversary

By Eileen De Guire / June 25, 2013

The Materials Genome Initiative aspires to reduce by half the time from materials discovery to manufacture. Credit: MGI; OSTP.    The Materials Genome Initiative turned two yesterday, and the White House celebrated the birthday by announcing a flurry of new projects that involve sizeable investments from 20 or so collaborators. According to a fact sheet (pdf)…

A diagram of proposed new solar panel design. The top layer of each photovoltaic cell is a conventional photo electrode. While most electrons flow out of the device to support a power load, some are directed to a polyvinylidene fluoride polymer (PVDF) coating on zinc oxide nanowires at the bottom, which serves as energy storage.…

Super-small erasable SketchSET transistor, ‘artificial atom’ could lead to super-big payoff

By Eileen De Guire / April 27, 2011

An atomic-scale depiction of the SketchSET shows three wires (green bars) converging on the central island (center green area), which can house up to two electrons. Electrons tunnel from one wire to another through the island. Conditions on the third wire can result in distinct conductive properties. Credit: Jeremy Levy, Univ. of Pittsburgh. Good news,…

New material to power tiny generators

By / October 24, 2009

Via press release from University of Wisconsin, we learn that a team of researchers has developed a piezoelectric nanogenerator and experimented with a variety of materials to power it. The team found that zinc oxide nanowires, which have six-sided, column-like crystals, could produce 10 nanowatts per square centimeter by converting mechanical energy into electricity. The…
