New Technology to Boost the Efficiency of Fuel Cells
Fuel cells, devices that can produce electricity from hydrogen or other fuels without burning them, are considered a promising new way of powering everything from homes and cars to portable devices like cellphones and laptop computers. Their big advantage — the prospect of eliminating emissions of greenhouse gases and other pollutants — has been outweighed by their very high cost, and researchers have been trying to find ways to make the devices less expensive.

New Silicon-based Material Proved to Increase Solar Cell Encapsulation Efficiency
Dow Corning® PV-6100 Encapsulant Series relies on the UV stability of the silicone molecule to deliver improved durability and increased efficiency for crystalline modules compared to incumbent organics. PV-6100 Encapsulant Series provide an ultra-transparent layer of protection for the solar cell in a panel and can replace incumbent technologies. The silicon-based material provides higher efficiency, longer module life, and optimum UV resistance.

Nanorod Crystals Finds Potential in Future Solar Cells with Increased Semiconductor Conductivity
In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have reported a technique by which the electrical conductivity of nanorod crystals of the semiconductor cadmium-selenide was increased 100,000 times.

High Power X-Ray responsible for Such Things as Fuel Cell Catalysts
What can you do with x-rays that are 10 billion times brighter than those from your doctor's x-ray machine? A lot! Scientists using the powerful beam lines at Berkeley Lab's Advanced Light Source in recent years have conducted breakthrough research on platinum-nickel alloys as a catalyst for fuel cells, made a discovery about the Ebola virus structure that could lead to a vaccine, and crafted a new technique for guiding self-assembly of nanostructures that should open up vistas for entirely new applications.

Findings Open The Door to Improved Microbial Fuel Cell Architecture
In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, Derek Lovley and colleagues at the University of Massachusetts Amherst supervised the evolution of a new strain that dramatically increases power output per cell and overall bulk power.
