Matched 'hybrid' systems may hold key to wider use of renewable energyWed, 26 Nov 2014 14:42:43 EST
The use of renewable energy in the United States could take a significant leap forward with improved storage technologies or more efforts to 'match' different forms of alternative energy systems that provide an overall more steady flow of electricity, researchers say in a new report. Physicists bind single-atom sheets with the same force geckos use to climb wallsTue, 25 Nov 2014 13:19:21 EST
The approach is to design synergistic materials by combining two single-atom thick sheets, for example, that act as a photovoltaic cell as well as a light-emitting diode, converting energy between electricity and radiation. Blu-ray disc can be used to improve solar cell performanceTue, 25 Nov 2014 11:18:16 EST
Who knew about Blu-ray discs? One of the best ways to store high-definition movies and television shows because of their high-density data storage, Blu-ray discs also improve the performance of solar cells, according to a new study. Researchers have discovered that the pattern of information written on a Blu-ray disc -- and it doesn't matter if it's Jackie Chan's 'Supercop' or the cartoon 'Family Guy' -- works very well for improving light absorption across the solar spectrum. Scientists get to the heart of fool's gold as a solar materialTue, 18 Nov 2014 18:25:00 EST
As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity. Theoretically, iron pyrite could do the job, but when it works at all, the conversion efficiency remains frustratingly low. Now, a research team explains why that is, in a discovery that suggests how improvements in this promising material could lead to inexpensive yet efficient solar cells. Revolutionary solar-friendly form of silicon shinesMon, 17 Nov 2014 13:06:13 EST
Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices -- carbon is to biology as silicon is to technology. Scientists have synthesized an entirely new form of silicon, one that promises even greater future applications.
