Tiny structure gives big boost to solar power
23 Dec | News at PrincetonFull Text External Link Indicator
"Princeton researchers have found a simple and economical way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power."
A Quantum Dot First: Electron-Photon Entanglement
29 Nov | IEEE SpectrumFull Text External Link Indicator
"Two different teams have shown, for the first time, that it’s possible to create entangled pairs of photons and electrons using quantum dots. The advance could help pave the way to practical quantum communication networks, which promise to be far more secure than today’s telecommunication networks."
Solar Innovation to Support "Energiewende"
05 Sep | HeliatekFull Text External Link Indicator
"Dresden, Germany, August 21, 2012 – Federal Environment Minister Peter Altmaier, along with Saxony’s Prime Minister, Stanislaw Tillich, visited Heliatek GmbH in Dresden on August 17, 2012. Heliatek’s innovative products will support the energy transformation towards sustainability in new ways never thought possible before.

Heliatek manufactures energy harvesting components made of flexible solar films based on organic semiconductor materials. The company inaugurated its first production facility last March in Dresden in the presence of Prime Minister Tillich. The state-of-the-art manufacturing line is now up and running, with the plant carrying out the scheduled trial production. This visit emphasizes the German Government’s commitment to continue to provide extensive support for the research and development of environmentally friendly energy technologies."
Plasmonic material bridges photonics, electronics gap
07 Aug | Photonics SpectraFull Text External Link Indicator
"WEST LAFAYETTE, Ind. – A thin film of titanium nitride was coaxed into transporting plasmons, becoming the first nonmetal to be added to the short list of surface-plasmon-supporting materials and bridging the gap between photonics and electronics. The nonmetal could pave the way to a new class of optoelectronic devices that have unprecedented efficiency and speed."
Super absorber could boost efficiency in solar cells
07 Aug | Photonics SpectraFull Text External Link Indicator
"EVANSTON, Ill. – A new material that absorbs a wide range of wavelengths could lead to more efficient, less expensive solar technology"
Sharp develops concentrator solar cell with efficiency of 43.5%
01 Aug | Semiconductor TodayFull Text External Link Indicator
"Japan’s Sharp Corp has used a concentrator triple-junction III-V compound semiconductor photovoltaic cell to achieve a solar energy conversion efficiency of 43.5%, equaling the record for concentrating conversion efficiency set in March 2011 by Solar Junction of San Jose, CA, USA, a manufacturer of III-V multi-junction solar cells for concentrated photovoltaics (CPV)."
Report: Two Solar Technologies That Will Thrive; Two On the Demise
01 Aug | Renewable Energy World.ComFull Text External Link Indicator
"New Hampshire, USA For every revolutionary advance in solar, there are countless evolutionary dead-ends — technologies that were well worth exploring, but ones that ultimately failed to live up to the mantra of "cut costs or die.""

Solar nanowire array may increase percentage of sun’s frequencies available for energy conversion
05 Jul | Sandia National LaboratoriesFull Text External Link Indicator
"Researchers creating electricity through photovoltaics want to convert as many of the sun’s wavelengths as possible to achieve maximum efficiency. Otherwise, they’re eating only a small part of a shot duck: wasting time and money by using only a tiny bit of the sun’s incoming energies."
New 'metamaterial' practical for optical advances
05 Jul | Purdue UniversityFull Text External Link Indicator
Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers and solar cells.
