Water and some nano-structured iron oxide is all it takes to produce bubbles of solar hydrogen. EPFL and Technion scientists just discovered the champion structure to achieve this In the quest for the production of renewable and clean energy, photoelectrochemical cells (PECs) constitute a sort of a Holy Grail. PECs are devices able of splitting water molecules into hydrogen and oxygen in a single operation, thanks to solar radiation. "As a matter of fact, we've already discovered this...

Sets New Record with Concentrator Triple-Junction Compound Solar Cell Osaka, June 14, 2013 - (JCN Newswire) - Sharp Corporation has achieved the world's highest solar cell conversion efficiency(2) of 44.4%(1), using a concentrator triple-junction compound solar cell. These solar cells are used in a lens-based concentrator system that focuses sunlight on the cells to generate electricity.This latest Sharp breakthrough came about through research and development...

Solar Power Through Painted On Organic Photovoltaics
2013-05-14 05:58:22

Lee Rannals for redOrbit.com - Your Universe Online Researchers at the University at Buffalo are developing a technique that could allow for solar panels to be painted on some day. The team wrote in the journal Advanced Materials they are helping to develop a new generation of photovoltaic cells that produce more power and cost less to manufacture than today's solar panels. These devices are processed in liquid form and can be applied to a variety of surfaces. “Compared with...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
