Power/Performance Bits: Nov. 15


Another record-breaking tandem perovskite solar cell University of California, Berkeley, and Lawrence Berkeley National Laboratory scientists report a new design for perovskite solar cells that achieves an average steady-state efficiency of 18.4%, with a high of 21.7% and a peak efficiency of 26%. "This has a great potential to be the cheapest photovoltaic on the market, plugging into any... » read more

Power/Performance Bits: Sept. 6


Carbon nanotube transistors outperform silicon University of Wisconsin-Madison materials engineers created carbon nanotube transistors that outperform silicon transistors, improving the current 1.9 times. The new transistors are particularly promising for wireless communications technologies that require a lot of current flowing across a relatively small area. "This achievement has been a... » read more

Power/Performance Bits: April 12


Digital storage in DNA Computer scientists and electrical engineers from University of Washington and Microsoft detailed one of the first complete systems to encode, store and retrieve digital data using DNA molecules, which can store information millions of times more compactly than current archival technologies. Progress in DNA storage has been rapid: in 1999, the state-of-the-art in DN... » read more
