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

New approach to switches According to the National Resource Defense Council, Americans waste up to $19 billion annually in electricity costs due to always-on digital devices in the home that suck power even when they are turned off. With that in mind, a team from University of Utah devised a new kind of switch for electronic circuits that uses solid electrolytes such as copper sulfide to ... » read more

Monoxide chips Two-dimensional (2D) materials are gaining steam in the R&D labs. The 2D materials could enable a new class of field-effect transistors (FETs), but the technology isn’t expected to appear until sometime in the next decade. The 2D materials include graphene, boron nitride and the transition-metal dichalcogenides (TMDs). One TMD, molybdenum diselenide (MoS2), is gaining inter... » read more

Memristors come in threes The race is on to produce a commercial memristor, and a duo from ETH Zurich may be providing a bit more push. "Basically, memristors require less energy since they work at lower voltages," explained Jennifer Rupp, professor in the Department of Materials at ETH Zurich. "They can be made much smaller than today's memory modules, and therefore offer much greater de... » read more

Quantum teleportation on a chip Researchers at the University of Tokyo have successfully integrated the core circuits of quantum teleportation, which generate and detect quantum entanglement, into silica-optical-waveguide circuits on a silicon photonic chip measuring 0.0001 square meters. While there has been significant progress in current technology of information processing, its perfor... » read more
