Scientists achieve first direct observations of excitons in motionWed, 16 Apr 2014 09:08:03 EDT
A quasiparticle called an exciton -- responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits -- has been understood theoretically for decades. But exciton movement within materials has never been directly observed. Now scientists have achieved that feat, imaging excitons' motions directly. This could enable research leading to significant advances in electronics, they say, as well as a better understanding of natural energy-transfer processes, such as photosynthesis. Scientists come up with method of reducing solar panel glareTue, 15 Apr 2014 08:44:19 EDT
The glare from solar farms could be a thing of the past, thanks to new research. Researchers have developed a multi-layer anti-reflection coating for glass surfaces, which reduces the sun's reflection from photovoltaic panels while at the same time improving their efficiency. It is applied using the same technology as that used for depositing anti-reflection coatings on eye glasses. House windows that double as solar panels? Shiny quantum dots brighten future of solar cellsMon, 14 Apr 2014 12:38:20 EDT
A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work. Scientists have demonstrated that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight. Better solar cells, better LED light and vast optical possibilitiesFri, 11 Apr 2014 10:29:33 EDT
Changes at the atom level in nanowires offer vast possibilities for improvement of solar cells and LED light. Researchers have discovered that by tuning a small strain on single nanowires they can become more effective in LEDs and solar cells. Passive houses save lots of energyFri, 11 Apr 2014 09:17:19 EDT
Housing is the easiest sector to change if we are to reach the climate targets, experts say. Norwegian research shows the housing sector today represents about one-third of the country's energy consumption, or about 35 terawatt hours out of a total of 112 terawatt hours. As a result, it is indirectly one of largest contributors to Norway's greenhouse gas emissions.
