THE GLOBAL HI-TECH ELECTRONICS PUBLICATION High-Efficiency Solar Cells


Los Alamos, NM — A new solution- based hot-casting technique devel- oped at Los Alamos National Labora- tory allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals.


Super-fast PSV7000 automat- ic programmer from Data I/O is one of many products being shown at NEPCON China with preview beginning on . . .

Perovskite Crystals “These perovskite crystals offer


promising routes for developing low- cost, solar-based, clean global energy solutions for the future,” said Aditya Mohite, the Los Alamos scientist leading the project. State-of-the-art photovoltaics us-


ing high-purity, large-area, wafer- scale single-crystalline semiconduc- tors grown by sophisticated, high tem- perature crystal-growth processes are seen as the future of efficient solar technology. Solar cells composed of or- ganic-inorganic perovskites offer effi- ciencies approaching that of silicon,

Perovskite occurs as a natural


mineral oxide as calcium titanate (CaTiO3). In work described in the journal Science, the researchers fabri- cated planar solar cells from per-


little cell-to-cell variability, resulting in devices showing hysteresis-free photovoltaic response, which had been a fundamental bottleneck for stable operation of perovskite devices.


Single-Atom Carbon Nanotubes to Boost Semicon Performance


Madison, WI —University of Wiscon- sin-Madison materials engineers have made a significant leap toward creating higher-performance elec- tronics with improved battery life, and the ability to flex and stretch. Led by materials science Asso-


ciate Professor Michael Arnold and Professor Padma Gopalan, the team


has reported the highest-performing carbon nanotube transistors ever demonstrated. In addition to paving the way for improved consumer elec- tronics, this technology could also have specific uses in industrial and military applications. In a paper published recently in


the journal ACS Nano, Arnold, Gopalan and their students reported transistors with an on-off ratio that’s 1,000 times better and a conductance that’s 100 times better than previous state-of-the-art carbon nanotube transistors.


Strong and Versatile “Carbon nanotubes are very


strong and very flexible, so they Continued on page 6


CEA Smart Grid Products Added to Catalog of Standards


Arlington, VA — According to the Consumer Electronics Association (CEA), the Recommended Practice for the Installation of Smart Grid De- vices, CEA/CEDIA-CEB29, has been added to the Smart Grid Interoper- ability Panel’s Catalog of Standards. Today’s homes include many products that connect to each other over a vari- ety of networks, and to operate reli- ably, both the products and the wiring to which they connect must be well protected and installed according to the manufacturer’s instructions. While CEB29 was written as a


recommended practice for the instal- lation of communicating smart grid devices in the home, all communicat- ing products — including home con- trols, AV, HVAC, computers and ap- pliances — are connected to the same electrical wiring and networks, and face the same installation chal- lenges. To remedy this, CEB29 com- bines information from many sources into a simple, accessible format that assumes no prior knowledge of the subject matter. “Whether you’re an electrician,


professional installer, consumer, or work for a manufacturer or a utility, this guide will provide the basic
