An abundant and inexpensive water-splitting photocatalyst with low toxicityWed, 16 Apr 2014 17:20:27 EDT
Researchers in Japan have discovered a new photocatalyst, Sn3O4, which facilitates the production of hydrogen fuel from water, using sunlight as an energy source. 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. Environmentally compatible organic solar cells in the futureWed, 16 Apr 2014 09:04:37 EDT
Environmentally compatible production methods for organic solar cells from novel materials are in the focus of “MatHero”. The new project aims at making organic photovoltaics competitive to their inorganic counterparts by enhancing the efficiency of organic solar cells, reducing their production costs and increasing their life-time. 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.
