THINNEST LIGHT ABSORBER

THINNEST LIGHT ABSORBER

Stanford university scientists have created the thinnest light absorber.
The nano size structure thousand of time thinner than ordinary sheet of paper, could lower the cost & improve the efficiency.
While reading up to this you can realize the reason behind the sharing of this information.
Yes it is the emerging trend, very effective way for utilizing our long lasting source i.e., solar energy.
The team at Stanford University achieved their goal that is making solar cell with very less material as well as low cost, without compromising its ability to absorb & connect sunlight into clean energy.
Thin wafers dotted with trillion round particles of gold. Each gold nano dots was about 14nm tall and 17nm wide.
They are fabricated by the technology called block-co polymer.
 An ideal solar cells can absorb visible light spectrum to invisible UV & IR rays where as gold nano dots can able to tune the absorption from one light from one light spot on spectrum
Eg: reddish- orange light was about 60nm long
