World record solar cell with 44.7% efficiency

German Fraunhofer Institute for Solar Energy Systems, Soitec, CEA-Leti and the Helmholtz Center Berlin announced today that they have achieved a new world record for the conversion of sunlight into electricity using a new ...

First all-carbon solar cell

(Phys.org)—Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today.

A new world record for solar cell efficiency

In a remarkable feat, scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have developed thin film solar cells on flexible polymer foils with a new record efficiency of 20.4 percent for ...

New paradigm for solar cell construction demonstrated

(Phys.org) —For solar panels, wringing every drop of energy from as many photons as possible is imperative. This goal has sent chemistry, materials science and electronic engineering researchers on a quest to boost the ...

IBM develops promising contender for cheaper solar cells

(PhysOrg.com) -- Solar cells could make fossil fuels virtually redundant if they were cheaper, but their use of rare elements and complex manufacturing processes makes them expensive. Now IBM Research has developed a prototype ...

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 ...
