New efficiency benchmark for dye-sensitized solar cells
In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells. (2008-06-30)
Argonne's Hard X-ray Nanoprobe provides new capability to study nanoscale materials
The Center for Nanoscale Materials' (CNM) newly operational Hard X-ray Nanoprobe at the U.S. Department of Energy's (DOE) Argonne National Laboratory is one of the world's most powerful x-ray microscopes. (2008-06-25)
Scorched Earth millenium map shows 'fire scars'
A geographer from the University of Leicester has produced for the first time a map of the scorched Earth for every year since the turn of the Millennium. (2008-05-23)
New efficiency record for solar cells
The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer. (2008-05-15)
Berkeley Researchers Identify Photosynthetic Dimmer Switch
In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular "dimmer switch" that helps control the flow of solar energy moving through the system of light harvesting proteins. (2008-05-09)
Scientists head to warming Alaska on ice core expedition
The state of Alaska has the dubious distinction of leading the lower 48 in the effects of a warming climate. Small villages are slipping into the sea due to coastal erosion, soggy permafrost is cracking buildings and trapping trucks. (2008-04-30)
On the Energy Trail: Berkeley Researchers Find New Details Following the Path of Solar Energy During Photosynthesis
Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. (2008-04-28)
Argonne scientists develop techniques for creating molecular movies
They may never win an Oscar, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now. (2008-04-16)
More safety for cell phone batteries
Fraunhofer researchers will be presenting a novel lithium-ion battery at Hannover Messe on April 21 - 25. It is based on a polymer electrolyte, which is - unlike the liquid electrolyte in conventional lithium-ion batteries - not inflammable. A test set-up for redox flow batteries will also be on display at the show. (2008-04-14)
Popcorn-ball design doubles efficiency of dye-sensitized solar cells
A new approach is able to create a dramatic improvement in cheap solar cells now being developed in laboratories. (2008-04-11)
