Solar energy gets a boost: 'Singlet fission' can increase solar cell efficiency by as much as 30 percentTue, 08 Jul 2014 13:21:46 EDT
Scientists have reviewed chemists' work on "singlet fission," a process in which a single photon generates a pair of excited states. This conversion process has the potential to boost solar cell efficiency by as much as 30 percent. Solar cells: Powered by nanoholesTue, 08 Jul 2014 11:10:17 EDT
Increasing the cost-effectiveness of photovoltaic devices is critical to making these renewable energy sources competitive with traditional fossil fuels. One possibility is to use hybrid solar cells that combine silicon nanowires with low-cost, photoresponsive polymers. A simple and inexpensive fabrication procedure boosts the light-capturing capabilities of tiny holes carved into silicon wafers. Orgainic solar modules embedded in glass last longerTue, 08 Jul 2014 09:21:40 EDT
Organic solar modules have advantages over silicon solar cells. However, one critical problem is their shorter operating life. Researchers are working on a promising solution: they are using flexible glass as a carrier substrate that better protects the components. Monitoring neighborhood electricity consumption over 24 hour cycleFri, 04 Jul 2014 13:46:29 EDT
With more and more households owning one or even two electric cars requiring charging overnight, how will we manage it without sacrificing our hot morning shower and fresh bread for breakfast? This is the headache now facing the electricity supply companies. But this isn’t their only problem. What use is it to those homeowners, who have installed a modest solar panel system on their roofs, when the sun is heating the pavement in the middle of the day and no one is at home to use the energy? Consider water use in climate change policies: Energy efficient technologies can also save water at the same timeThu, 03 Jul 2014 10:26:05 EDT
There’s more to trying to slow down climate change than just cutting greenhouse gas emissions. Technology, policies or plans that aim to do so should also take environmental factors such as water usage into account. A more integrated approach might make some options considerably more attractive than others, especially when implemented in arid countries such as Australia.
