Japan firm develops 'sun-chasing' solar panels

A new Japanese solar power device can generate twice the electricity of current models thanks to moving mirrors that follow the sun throughout the day, according to its developers.

Microwave oven cooks up solar cell material

University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient ...

The topolariton, a new half-matter, half-light particle

A new type of "quasiparticle" theorized by Caltech's Gil Refael, a professor of theoretical physics and condensed matter theory, could help improve the efficiency of a wide range of photonic devices—technologies, such as ...

Future looks bright for carbon nanotube solar cells

(Phys.org) —In an approach that could challenge silicon as the predominant photovoltaic cell material, University of Wisconsin-Madison materials engineers have developed an inexpensive solar cell that exploits carbon nanotubes ...

Engineer pursues biological solar power

A Binghamton University engineering researcher designed a biological solar cell that's a million times more effective than current technology. Preliminary data on Seokheun "Sean" Choi's next advancement is a thousand times ...

Turning windows into powerplants

If a new development from labs at MIT pans out as expected, someday the entire surface area of a building’s windows could be used to generate electricity — without interfering with the ability to see through them.
