Scientists Find Strange New Effect for Future Solar Cells: Flexo-photovoltaics

Poking something sharp into a plain silicon crystal turns it into a solar cell that might shoot past today’s efficiency limits Illustration: Mark Garlick/University of Warwick Scientists at the University of Warwick report that they’ve discovered a new kind of photovoltaic effect. What they dub “flexo-photovoltaics” is really the realization that…

How to Bend Diamonds

Flexible nanodiamonds promise to open up novel optical and electronic properties Image: Yang Lu, Amit Banerjee, Daniel Bernoulli, Hongti Zhang, Ming Dao and Subra Suresh It’s commonly known that diamonds are the hardest natural material. However, with that hardness comes brittleness: they may be hard but they’re not very flexible.…
