Most simple solar cells handle the bluish hues of the electromagnetic spectrum inefficiently. This is because blue photons — incoming particles of light that strike the solar cell — actually have excess energy that a conventional solar cell can’t capture. Click to enlarge.
New solar cell technology captures high-energy photons more efficiently

Scientists at Argonne and the University of Texas at Austin have together developed a new, inexpensive material that has the potential to capture and convert solar energy — particularly from the bluer part of the spectrum — much more efficiently than ever before.

Good hair day: New technique grows tiny 'hairy' materials at the microscale

Scientists at Argonne attacked a tangled problem by developing a new technique to grow tiny “hairy” materials that assemble themselves at the microscale.

Typically, the process of corrosion has been studied from the metal side of the equation. Click to enlarge.
The core of corrosion

Most times, the effects of corrosion are studied with regard to the metal surface. In a new study, researchers looked at the effects that corrosion has on the water and dissolved ions doing the corroding.

Atomic carbon (black spheres) is evaporated at over 2,300 degrees Celcius and deposited on a silver platform where flakes of graphene form. Lighter-colored regions correspond to graphene growth and silver is depicted in the darker regions. Click to enlarge.
Silver linings: Argonne scientists are first to grow graphene on silver

Researchers discover a new method to growing graphene on silver opening the door to new physics and device applications.

Argonne scientists in collaboration with researchers from Arizona State University have found a way to imitate Photosystem II, the first protein complex in the long chain of reactions that use energy from the sun to create usable fuel. Click to enlarge.
Photosynthesis, reimagined

Scientists at the U.S. Department of Energy's Argonne National Laboratory in collaboration with researchers from Arizona State University have found a way to imitate Photosystem II, the first protein complex in the long chain of reactions that use energy from the sun to create usable fuel.

Flexible, transparent thin film transistors raise hopes for flexible screens

The electronics world has been dreaming for half a century of the day you can roll a TV up in a tube. But scientists got one step closer last month when researchers at Argonne reported the creation of the world’s thinnest flexible, see-through 2-D thin film transistors.

Microscopy charges ahead

In order to see the true polarization states of ferroelectric materials quickly and efficiently, researchers at the U.S. Department of Energy’s Argonne National Laboratory have developed a new technique called charge gradient microscopy.

Solar panel manufacturing is greener in Europe than China, study says

Solar panels made in China have a higher overall carbon footprint and are likely to use substantially more energy during manufacturing than those made in Europe, said a new study from Northwestern University and Argonne.

Thin diamond films provide new material for micro-machines

Researchers at the Center for Nanoscale Materials at the U.S. Department of Energy’s Argonne National Laboratory and a handful of other institutions around the world have directed their focus to exploring microelectromechanical systems made of a relatively new material known as ultrananocrystalline diamond, which is a smooth and wear-resistant diamond thin film.
