Smaller Particles Could Mean More Efficient Solar Panels
Studies done by Mark Lusk and colleagues at the Colorado School of Mines could significantly improve the efficiency of solar cells. Their latest work describes how the size of light-absorbing particles–quantum dots–affects the particles’ ability to transfer energy to electrons to generate electricity.
The results are published in the April issue of the journal ACS Nano.
The advance provides evidence to support a controversial idea, called multiple-exciton generation (MEG), which theorizes that it is possible for an electron that has absorbed light energy, called an exciton, to transfer that energy to more than one electron, resulting in more electricity from the same amount of absorbed light.

Kudos to you…I have often theorized such capability myself….
Now my next question is…
If this is possible then why not take the Idea that the Fractal Antenna did for the drawing in of RF signal or radio waves and take this same theory and apply to Photons. If not… why Not?
It revolutionized the ability to increase the signal strength so why not the Photons draw?
Harnessing more Photons?
