A Low-Cost Manufacturing Solution for CIGS-Based Solar Cells

Though the solar industry today predominately produces solar panels made from crystalline silicon, they remain relatively expensive to make. New players in the solar industry have instead been looking at panels that can harvest energy with CIGS (copper-indium-gallium-selenide) or...

Light emitting diodes (LEDs) and solid state lighting (SSL) products that incorporate LEDs pose many measurement challenges compared with other lighting elements, such as traditional...

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international...

Saving Energy With Artifical Noise

Ecological and economic factors are prompting telecommunications companies to deploy energy-saving systems. Scientists at Germany's Fraunhofer Institute for Communication Systems ESK provide a solution...

Scientists have developed a new hydrogen storage method - carbonized chicken feather fibers - that can hold vast amounts of hydrogen, and do it at a far lower cost than other hydrogen storage...

Renewable energy will be the world’s fastest-growing source of electricity generation over the next two decades, although it will still make up a relatively minor portion...

A new “virtual refrigerant charge sensor" saves energy and servicing costs by indicating when air conditioners are low on refrigerant, preventing the units from working overtime....

Researchers with Berkeley Lab and the University of California (UC) Berkeley have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass. This procedure, if it...

Researchers at the University of Chicago and Lawrence Berkeley National Laboratory have developed an “electronic glue” that could speed up advances in...

News of the world's first full-scale floating windmill being built spread over a year ago. Now, the Hywind has reached its final destination, where it will face rigorous...

New flexible solar cell technology, developed by engineering researchers at McMaster University of Hamilton, Ontario, has been installed in a campus bus shelter to provide power lighting...

In the near future, a crumbling parking lot in downtown Dallas, Texas will be the location of the first fully sustainable, urban square block in the United States. Re:Vision Dallas is...

Quantum-Well Thermophotovoltaic Cells

Thermophotovoltaic cells containing multiple quantum wells have been invented as improved means of conversion of thermal to electrical energy. These cells are expected to be especially useful for extracting electrical energy from combustion, waste-heat, and nuclear sources. Conversion efficiencies more than...

Briefs: Energy
Electromagnetically Clean Solar Arrays
The term “electromagnetically clean solar array” (EMCSA) refers to a panel that contains a planar array of solar photovoltaic cells. The cells are laminated with shielding, narrow-current-loop wiring, and structural supports. EMCSAs could be useful in applications that require limited electromagnetic interference.
