Using amorphous and monocristalline silicon together, EPFL team achieved an astounding 22.4 percent efficiency In the medium term, an investment of only $2500 in photovoltaic cells would suffice to provide more than enough electricity for the consumption of a four people household. This promising scenario has been made possible by the innovations accomplished by EPFL's Institute of Microengineering in Neuchatel. The team of prof. Christophe Ballif, director of the Photovoltaics Laboratory...

ZnSnP2, an absorber material for solar cells, transitions from an ordered to a disordered structure at high temperatures. Researchers from University College London and the University of Bath have proposed taking advantage of this structural change to design high-efficiency solar absorbers. The team used theoretical calculations to investigate the electronic structure of both phases, and predicted a significant difference in the bandgap between the ordered and fully disordered materials....

Nanotech Jump For Solar Cells

Solar power cells are limited by the wavelengths of light they can absorb from the sun. Ideally a solar cell would absorb every wavelength, but to date the goal has not been reached. Silicon, today's photovoltaic industry standard, is limited in the wavelength range it can 'see' and absorb. A possible solution has been found in indium gallium nitride. Using this material, scientists can tune the material's response so it collects solar energy from a variety of wavelengths. The more...

First Genetically Evolved Semiconductor Material Synthesized

In the not-too-distant future, scientists may be able to use DNA to grow their own specialized materials, thanks to the concept of directed evolution. UC Santa Barbara scientists have, for the first time, used genetic engineering and molecular evolution to develop the enzymatic synthesis of a semiconductor. "In the realm of human technologies it would be a new method, but it's an ancient approach in nature," said Lukmaan Bawazer, first author of the paper, "Evolutionary selection of...

Word of the Day
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
