Thin cells for solar energy
A new type of very thin solar cell made from inexpensive materials has been invented by researchers at the Hahn Meitner Institute in Berlin, Germany, in collaboration with a colleague now at Portland State University, Oregon, USA. The new device will be much cheaper to make because it uses less expensive semiconductor materials than conventional solar cells. The researchers publish details of their invention in the Institute of Physics journal Semiconductor Science & Technology on 14 April 2003.
Ames Laboratory Researchers Hope to "Sunproof" Solar Cells
Computer Simulations Provide Insight On Light Degradation Effect in Solar Cells
Scientists at the U.S. Department of Energy’s Ames Laboratory and Iowa State University’s Microelectronics Research Center may have solved a mystery that has plagued the research community for more than 20 years: Why do solar cells degrade in sunlight? Finding the answer to that question is essential to the advancement of solar cell research and the ability to produce lower-cost electricity from
Power plant technology breakthrough with Finnish know how
VTT’s new device promotes clean combustion technology with high plant efficiency
VTT, Technical Research Centre of Finland, offers new opportunities to improve power plant efficiency with its globally unique research equipment. Most power plant types, independent of their fuel, use steam to produce energy. The first of its kind, VTT’s equipment now enables steam to be brought to its supercritical state under research conditions. In this state, the steam may reach a temperatu
Z produces fusion neutrons, Sandia scientists confirm
Huge pulsed power machine enters fusion arena
Throwing its hat into the ring of machines that offer the possibility of achieving controlled nuclear fusion, Sandia National Laboratories’ Z machine has created a hot dense plasma that produces thermonuclear neutrons, Sandia researchers announced today at a news conference at the April meeting of the American Physical Society in Philadelphia.
The neutrons emanate from fusion reactions within a BB-sized deuterium capsule pla
Photonic crystals to improve microwave circuits
The principal aim of this PhD paper was the application of the new concepts and ideas of Photonic Crystals and Photonic Bandgap (PBG) to microwave and millimetric circuits and, more concretely, to microstrip circuits which is the most common technology in current use in flat microwave circuits.
Thus, for this thesis, the techniques for optimising the functioning of PBG structures in microstrip technology were studied and the various practical applications of these devices were analysed. For
Sunny times ahead for cheaper solar power
Greater use of clean electricity from the sun should be a step closer, thanks to new research carried out in the UK.
The research has shown how the cost of generating solar electricity can be reduced, laying the foundation for a major expansion in the use of this sustainable energy technology.
The project has been undertaken by a team of physicists, chemists, material scientists and engineers at Sheffield Hallam University, with funding from the Swindon-based Engineering and
