Team optimizes formula for cadmium-tellurium solar cells

Solar cells based on cadmium and tellurium could move closer to theoretical levels of efficiency because of some sleuthing by researchers at the Department of Energy's Oak Ridge National Laboratory.

Type of ice reveals the age of comets

The ice buried inside comet 67P/ Churyumov-Gerasimenko is mainly found in crystalline form, which implies that it originated in the protosolar nebula and is therefore the same age as the Solar System. This discovery was made ...

Physicists discover new properties of superconductivity

New findings from an international collaboration led by Canadian scientists may eventually lead to a theory of how superconductivity initiates at the atomic level, a key step in understanding how to harness the potential ...

Researchers create perovskites via mechanochemistry

Perovskites, substances that perfectly absorb light, are the future of solar energy. Now, a rapid and environmentally safe method of production has been developed by chemists from Warsaw, Poland. Perovskites can now be synthesized ...
