Researchers Look To New Process To Harvest Solar Energy
2013-02-25 15:25:57

Peter Suciu for redOrbit.com — Your Universe Online Since the seventh century B.C., mankind has looked to the power of the sun to provide an energy source. In the earliest days, humans used glass and mirrors to concentrate the sun's rays to make fire. Later, around the first century A.D., the Romans discovered large south facing windows could help let in the sun´s warmth. There's even one infamous tale of Greek scientist Archimedes using bronze shields to reflect and focus...

Researchers at the Vienna University of Technology show that a recently discovered class of materials can be used to create a new kind of solar cell. Single atomic layers are combined to create novel materials with completely new properties. Layered oxide heterostructures are a new class of materials, which has attracted a great deal of attention among materials scientists in the last few years. A research team at the Vienna University of Technology, together with colleagues from the USA...

A 10.7 percent conversion rate has been achieved using less than 2 micrometers of raw material The Photovoltaics-Laboratory (PV-Lab) of EPFL's Insitute of Microengineering (IMT), founded in 1984 by Prof. Arvind Shah and now headed by Prof. Christophe Ballif, is well known as a pioneer in the development of thin-film silicon solar cells, and as a precursor in the use of microcrystalline silicon as a photoactive material in thin-film silicon photovoltaic (TF-Si PV) devices. A remarkable step...

Geometric pattern maximizes time light is trapped in solar cell The sun´s energy is virtually limitless, but harnessing its electricity with today´s single-crystal silicon solar cells is extremely expensive – 10 times pricier than coal, according to some estimates. Organic solar cells – polymer solar cells that use organic materials to absorb light and convert it into electricity – could be a solution, but current designs suffer because polymers have...

Nanowires More Efficient Than Solar Cells
2013-01-18 19:23:18

Lee Rannals for redOrbit.com — Your Universe Online A team from Lund University in Sweden wrote in the journal Science about how nanowires could eventually make way for more efficient solar cells. Scientists have been studying solar cell nanowires more and more, and until now, the dream figure was ten percent efficiency. However, the Swedish researchers were able to report an efficiency of 13.8 percent. Nanowires are made of the semiconductor material indium phosphide and work...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
