Major advances in dye sensitized solar cellsTue, 22 Apr 2014 12:07:59 EDT
Two groups of researchers have recently advanced the field of solar cells with a cheaper and efficient replacement for platinum and better synthesis of zinc oxide. Working on dye-sensitized solar cells -- researchers in Malaysia have achieved an efficiency of 1.12%, at a fraction of the cost compared to those used by platinum devices. Quantum simulators developed to study inaccessible physical systemsTue, 22 Apr 2014 11:33:07 EDT
Quantum simulators recreate the behavior on a microscopic scale of biological and quantum systems and even of particles moving at the speed of light. The exact knowledge of these systems will lead to applications ranging from more efficient photovoltaic cells to more specific drugs. Researchers are working on the design of several of these quantum simulators so they can study the dynamics of complex physical systems. Like a hall of mirrors, nanostructures trap photons inside ultrathin solar cellsTue, 22 Apr 2014 10:00:15 EDT
In the quest to make sun power more competitive, researchers are designing ultrathin solar cells that cut material costs. At the same time they're keeping these thin cells efficient by sculpting their surfaces with photovoltaic nanostructures that behave like a molecular hall of mirrors. Higher solar-cell efficiency achieved with zinc-oxide coatingTue, 22 Apr 2014 08:45:15 EDT
Researchers have achieved 14-percent efficiency in a 9-millimeter-square solar cell made of gallium arsenide. It is the highest efficiency rating for a solar cell that size and made with that material. An abundant and inexpensive water-splitting photocatalyst with low toxicityWed, 16 Apr 2014 17:20:27 EDT
Researchers in Japan have discovered a new photocatalyst, Sn3O4, which facilitates the production of hydrogen fuel from water, using sunlight as an energy source.
