Experiments show dramatic increase in solar cell output

In any conventional silicon-based solar cell, there is an absolute limit on overall efficiency, based partly on the fact that each photon of light can only knock loose a single electron, even if that photon carried twice ...


A stretchy display for shapable electronics

No one would ever imagine crumpling up their smartphone, television or another electronic device. Today's displays—which are flat, rigid and fragile—lack the ability to reshape to interactively respond to users.

An ironclad future for solar arrays

Solar energy plays an important role in the fight against climate change as a substitute for fossil fuels. Dye-sensitized solar cells promise to be a low-cost supplement to the photovoltaic systems we know today. Their key ...
