Researchers have found irrefutable proof that the so-called avalanche effect by electrons occurs in specific, very small semiconducting crystals.
This physical effect could pave the way for cheap, high-output solar cells. One possible improvement could derive from a new type of solar cell made of semiconducting nanocrystals (crystals with dimensions in the nanometre size range).
In conventional solar cells, one photon (light particle) can release precisely one electron.
New European Record Efficiency For Solar Cells...
At 39.7% efficiency for a multi-junction solar cell, researchers at the Fraunhofer Institute for Solar Energy Systems have exceeded their own European record of 37.6% which they achieved just...
Perfecting A Solar Cell By Adding Imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with...

The Black Hole War: My Battle with Stephen Hawking to...
What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed it did-and in doing so put at risk everything we...
