Bumpy liquid films could simplify fabrication of microlensesThu, 11 Feb 2016 13:36:28 EST
Have you ever noticed that when heated a film of oil in a pan doesn’t remain completely flat? Instead, it forms a wavy pattern that resembles the exterior of an orange. These sorts of deformations inspired a group of researchers to explore whether they could be used to improve and streamline microfabrication processes. An interaction between perovskites and quantum dots could improve LED and solar technologiesTue, 09 Feb 2016 09:07:12 EST
Researchers have studied the interaction of two materials, halide perovskite and quantum dots, revealing enormous potential for the development of advanced LEDs and more efficient solar cells. Claims for solar cell efficiency put to the testMon, 08 Feb 2016 12:48:55 EST
The sheet of paper taped to the door of Keith Emery's office tells the story. On the paper is a simple fever chart showing the improvements made in increasing the efficiency of two dozen types of solar cells. Some of the lines marking record efficiencies date to the mid-1970s. Others start much more recently, with the advent of newer technologies. Host-guest nanowires for efficient water splitting and solar energy storageWed, 03 Feb 2016 08:58:40 EST
California is committed to 33 percent energy from renewable resources by 2020. With that deadline fast approaching, researchers across the state are busy exploring options. Solar energy is attractive but for widespread adoption, it requires transformation into a storable form. This week researchers report that nanowires made from multiple metal oxides could put solar ahead in this race. Breakthrough enables ultra-fast transport of electrical charges in polymersThu, 28 Jan 2016 11:38:19 EST
For the first time, researchers have shown that a very efficient vertical charge transport in semiconducting polymers is possible by controlled chain and crystallite orientation. These pioneering results enhance charge transport in polymers by more than 1,000 times, have implications for organic opto-electronic devices.
