Power/Performance Bits: May 10


Non-toxic thin-films A team at Australia's University of New South Wales achieved the world's highest efficiency using flexible solar cells that are non-toxic and cheap to make, with a record 7.6% efficiency in a 1cm2 area thin-film CZTS cell. Unlike its thin-film competitors, CZTS cells are made from abundant materials: copper, zinc, tin and sulphur, and has none of the toxicity problems... » read more

System Bits: July 9


New quantum computing algorithm Researchers at the University of California, San Diego, have proposed a new algorithm for quantum computing that they believe will speed a particular type of problem…but swifter calculations would come at the cost of greater physical resources devoted to precise timekeeping. The algorithm would be used to conduct a task called an unstructured search. The go... » read more
