A semi-artificial leaf faster than 'natural' photosynthesisWed, 20 Aug 2014 09:16:07 EDT
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. Solar energy that doesn't block the viewTue, 19 Aug 2014 20:02:19 EDT
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 devicesTue, 19 Aug 2014 11:29:56 EDT
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 cellsMon, 18 Aug 2014 11:34:28 EDT
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. Insights into a new class of semiconducting materialsTue, 12 Aug 2014 16:35:29 EDT
A new paper describes investigations of the fundamental optical properties of a new class of semiconducting materials known as organic-inorganic 'hybrid' perovskites.
