Energy efficiency bill wins bi-partisan support

The strangest of things took place in Washington, D.C., on Wednesday: The House of Representatives passed apparently meaningful energy-related legislation with true bipartisan support.

Improving solar power’s efficiency

First Solar is apparently inching toward manufacturing some silicon solar products, but that doesn’t mean the company’s bread and butter, cadmium-telluride (CdTe) cells, are taking a back seat. Not if this news is any indication: a new CdTe cell conversion record of 20.4 percent.

A simple, cheap way to increase solar cell efficiency

Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification can increase solar cell efficiency by more than 30 percent.

Big beats bolster solar cell efficiency

Playing pop and rock music improves the performance of solar cells, according to new research from scientists at Queen Mary University of London and Imperial College London.

Breakthrough claimed for solar cell efficiency

Did you know that crystals form the basis for the penetrating icy blue glare of car headlights and could be fundamental to the future in solar energy technology?

Solar power beats biofuels for powering cars

Photovoltaics (PV) technology is much more efficient than biomass at fuelling a car, say researchers, making a mockery of the US 2005 energy bill that calls for more use of corn ethanol as a biofuel.

Solar panels efficiency bolstered by green roofs

It’s not surprise that having both a green roof and a solar panel array on a building is a great way to double down on reducing energy bills for property owners.

Big boost for solar cell efficiency

Princeton researchers say they've found a cheap and simple way to nearly triple the efficiency of organic solar cells.

Ford Fusion hybrid gets top fuel efficiency marks

American automaker Ford was recently crowing about its upcoming Fusion Hybrid.

Microbial fuel cells become 50 times more efficient

Engineers say they've developed microbial fuel cells that can produce up to 50 times more electricity directly from wastewater as previous efforts.

New biofuel process offers vast efficiency boost

A new biofuel production process is claimed to produce more than 20 times as much energy than existing methods.

DARPA wants robots with more stamina

The trouble with robots, says DARPA, is that no matter how good they are, they have an annoying tendency to run out of juice. It's no good carrying heavy equipment halfway to where it's needed; even worse is a robot that gets halfway though disarming a roadside bomb.

Small-scale fuel cell designed for the home

Individual homes could soon be powered with their own solid oxide fuel cell systems, thanks to a breakthrough in performance.

Luminescent solar cell breaks efficiency record

Totally counter-intuitively, solar cells that emit light as well as absorbing it could actually mr much more efficient.

Tandem polymer solar cells set energy-conversion record

UCLA scientists say they've significantly enhanced polymer solar cells' performance by building a new 'tandem' device that combines multiple cells with different absorption bands.

Team beefs up solar cell efficiency

University of Cambridge scientists have developed a new type of solar cell that could increase the maximum efficiency of solar panels by over 25 percent.

Desalination could be made cheaper, says team

Desalination of seawater could be the best way to solve the world's water shortage, say Yale researchers, who have come up with ways to improve its efficiency.

Energy savings helps military make money

The U.S. military has put an increasing emphasis on eco-friendly ops in recent years, and now Fort George G. Meade in Maryland is joining that effort.

Solar panel boosts efficiency four-fold

A University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light - compared with the 20 percent or so achieved by most current solar panels.

Viruses do assembly work for solar cells

Researchers at MIT have enlisted viruses to help assemble solar cells and improve their performance.
