New Solar Cells Shine With Potential
2012-05-24 11:34:04

Today´s solar cells have several limitations, including high production costs, low efficiency and durability, and reliance on scarce materials for production. Now, a group of Northwestern University researchers say they have developed a new solar cell that minimizes these problems. The device uses a Grätzel cell, a promising low-cost and environmentally friendly solar cell with a significant disadvantage: it leaks. The dye-sensitized cell's electrolyte is made of an...

Automotive, chemical, brick and glass industries could benefit from scientific discovery Researchers at Northwestern University have placed nanocrystals of rock salt into lead telluride, creating a material that can harness electricity from heat-generating items such as vehicle exhaust systems, industrial processes and equipment and sun light more efficiently than scientists have seen in the past. The material exhibits a high thermoelectric figure of merit that is expected to enable 14...

U.S. chemists say they've developed a class of new porous materials that are very effective at purifying hydrogen by separating it from complex gas mixtures. Northwestern University Professor Mercouri Kanatzidis and postdoctoral researcher Gerasimos Armatas said their new materials exhibit excellent selectivity in separating hydrogen from carbon dioxide and methane. A more selective process means fewer cycles to produce pure hydrogen, increasing efficiency, said Kanatzidis. Our materials...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
