Researchers working with copper indium gallium diselenide (CIGS) solar cells reported a 20.4 percent efficiency result on flexible polymer films, a level that underscores how far high-performance thin ...

Scientists at Japan’s National Institute of Advanced Industrial Science & Technology (AIST) have set ...

Copper is an essential micronutrient that serves as a cofactor for numerous enzymes, playing a vital role in processes ranging from cellular respiration to antioxidant defence. Eukaryotic cells employ ...

Researchers in Japan have achieved a 12.28% efficiency in a copper gallium selenide solar cell, the highest reported for indium-free wide-bandgap chalcogenide absorbers in the 1.65–1.75 eV range. The ...

A group of scientists from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) has fabricated a solar cell based on an absorber made of copper indium sulfide (CuInS 2), a ...

While toxic in high concentrations, copper is essential to life as a trace element. Many tumors require significantly more copper than healthy cells for growth—a possible new point of attack for ...

Engineering researchers at the University of Toronto have designed a new way to recycle steel that addresses copper and carbon impurities, according to a report by Safa Jinje for UofT Engineering News ...
