A Q&A with Rachel Goldman
The “Magic Ratio” that could power tomorrow’s solar cells
Nanoparticles could spur better LEDs, invisibility cloaks
More efficient LED lighting and invisibility cloaking are two possible applications for a new process that adds metallic nanoparticles to semiconductors.
‘Magic’ alloy could spur the next generation of solar cells
A new alloy could reduce the cost of high-efficiency solar cells called “concentrator photovoltaics.”
