Community Colleges: Preparing the Future Photonics Workforce
Aug 5, 2016 — World-renowned astronomer Carl Sagan once said, “Somewhere, something incredible is waiting to be known.” Community college photonics and optics programs are preparing students to find it. About 30 community colleges around the U.S....
Solar Cell Stores Energy, Too
COLUMBUS, Ohio, Oct. 7, 2014 — Solar cells could soon double as rechargeable batteries, greatly enhancing their power and efficiency.
New Polymer Mix Crafts More Efficient Solar Cells
CHICAGO and LEMONT, Ill., Sept. 22, 2014 — An enhanced polymer-based device could boost solar power generation and improve the efficiency of solar cells. The new device, developed by a team from the University of Chicago’s Institute for Molecular Engineering in collaboration with...
Nuclear Spins Boost Electric Current in OLEDs
SALT LAKE CITY, Sept. 19, 2014 — A spintronic approach has been used to power plastic organic LEDs at room temperature and without strong magnetic fields. “We have shown we can use room-temperature, plastic electronic devices that allow us to see the orientation of the...
Video: Cell Phones Become Microscopes with 3-D Printing
RICHLAND, Wash., Sept. 17, 2014 — 3-D printing could help turn cell phones into high-powered microscopes, enabling them to identify biological samples in the field. A team at the U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL) used a 3-D printer to create a...
Highest Conversion Efficiency Reached
TEMPE, Ariz., Aug. 7, 2014 — First Solar Inc. announced it has set a record for cadmium-telluride (CdTe) photovoltaic research cell conversion efficiency. The record has been documented in the U.S. Department of Energy's National Renewable Energy Laboratory "Best Research Cell...
New Spectroscopy Technique Probes Photochemical Reactions
BERKELEY, Calif., June 18, 2014 — Photochemical reactions have become key players in high technology, namely in the development of nanomaterials and solar energy systems. Better understanding of these light-triggered processes could lead to more efficient use. A team from Lawrence...
Photo-Induced Doping Tames Graphene
BERKELEY, Calif, June 6, 2014 — Doping graphene with boron nitride may be a way to tame the material, introducing a bandgap and making it useful in electronic devices. However, controlling the electrical properties of graphene boron nitride (GBN) heterostructures has been tricky....
Dark Matter Measures Age of Universe
DAVIS, Calif., March 23, 2010 — Astronomers from the United States and Europe have used a gravitational lens – a distant, light-bending clump of dark matter – to make a new estimate of the Hubble constant, which determines the size and age of the universe. The Hubble constant...
Lasers Analyze Coal Plants
BETHLEHEM, Pa., Sept. 9, 2008 – With worldwide demand for coal surging in the wake of ballooning gasoline prices, it’s no wonder more attention hasn’t been given to the sharp rise in coal cost – nearly doubling in less than a year. Several key factors play into the recent rise in...
Seeing an Extreme Universe
WASHINGTON, D.C., Aug. 27, 2008 – Passing its first orbital checkpoint with flying colors, NASA’s Gamma-Ray Large Area Space Telescope (GLAST) has revealed an entire gamma-ray sky. More than two months ago, NASA launched the GLAST with the hope of exploring the universe in...
Deadline Extended for SSL Product Development Funding
Jul 10, 2008 — The deadline for the Solid-State Lighting (SSL) Product Development (Round 5) funding opportunity has been extended from Friday, June 27 until Wednesday, July 16, 2008, at 3 p.m. EST. The U.S. Department of Energy released this funding opportunity...
