New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.
What makes cities in India and China so frustrating to drive in—heavy traffic, aggressive driving style, few freeways—makes them ideal for saving fuel with hybrid vehicles, according to new research by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
University of Cincinnati researchers are discovering how to manipulate light to one day better view the world’s tiniest objects through a super-lens, as well as how to hide an object in plain sight.
Converting sunshine into electricity is not difficult, but doing so efficiently and on a large scale is one of the reasons why people still rely on the electric grid and not a national solar cell network.
Most solar cells used in homes and industry are made using thick layers of material to absorb sunlight, but have been limited in the past by relatively high costs. Many new, lower cost designs are limited as their layer of light-absorbing material is too thin to extract enough energy.
Limited availability of fossil fuels stimulates the search for different energy resources. The use of biofuels is one of the alternatives. Sugars derived from the grain of agricultural crops can be used to produce biofuel but these crops occupy fertile soils needed for food and feed production.
Efficient is better than not efficient. More efficiency is better than less. In case you’re wondering, there is a light at the end of this tunnel, and I’m pretty sure it looks like the Zero Home.
The latest idea for producing hydrogen efficiently and without emissions drawbacks uses the sun in a setup that looks a lot like the big power-tower concentrating solar power plants that are nearing completion in the American Southwest.
Vehicles and infrastructures exchanging information with one another and notifying drivers about dangers and traffic situations reportedly make traffic safer and more efficient.
ARM currently dominates the lucrative mobile market (smartphones and tablets) with its low-power sipping RISC chips. And Intel?
