Competition for graphene: Researchers demonstrate ultrafast charge transfer in new family of 2-D semiconductors
The first experimental observation of ultrafast charge transfer in photo-excited MX2 materials, the graphene-like two-dimensional semiconductors, has been conducted. Charge transfer time clocked in at under 50 femtoseconds, comparable to the fastest times recorded for organic photovoltaics.
Cooperation between chemists and biologists has resulted in a new method for the very efficient integration of photosynthetic proteins in photovoltaics. Their research offers a new immobilization strategy that yields electron transfer rates exceeding for the first time rates observed in natural photosynthesis. This discovery opens the possibility for the construction of semi-artificial leaves functioning as photovoltaic devices with drastically increased performance.
Researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a flat, clear surface.
Organic photovoltaic cells of the future: Using charge formation efficiency to screen materials for future devices
Organic photovoltaic cells -- a type of solar cell that uses polymeric materials to capture sunlight -- show tremendous promise as energy conversion devices, thanks to key attributes such as flexibility and low-cost production, but have complex power conversion processes. To maneuver around this problem, researchers have developed a method to determine the absolute value of the charge formation efficiency. The secret of their method is the combination of two types of spectroscopy.
Recycling old car batteries into solar cells: Environmental twofer could recycle lead batteries to make solar cells
This could be a classic win-win solution: A system proposed by researchers recycles materials from discarded car batteries -- a potential source of lead pollution -- into new, long-lasting solar panels that provide emissions-free power.
A new paper describes investigations of the fundamental optical properties of a new class of semiconducting materials known as organic-inorganic 'hybrid' perovskites.
Materials chemists, polymer scientists and device physicists have reported on a breakthrough technique for controlling assembly of nanoparticles over multiple length scales that may allow cheaper, ecologically friendly manufacture of organic photovoltaics and other electronic devices.
The Columbia River basin in the Pacific Northwest offers great potential for water power; hydroelectric power stations there generate over 20,000 megawatts already. Now a simulation model will help optimize the operation of the extensive dam system.
