Power/Performance Bits: May 19


3D microbatteries for large-scale on-chip integration By combining 3D holographic lithography and 2D photolithography, researchers from the University of Illinois at Urbana-Champaign created a high-performance 3D microbattery suitable for large-scale on-chip integration with microelectronic devices. According to Paul Braun, professor of materials science and engineering at Illinois, "Micr... » read more

Power/Performance Bits: June 24


Solar-cell efficiency in one step Rice University scientists have created a single-step process for producing highly efficient materials that let the maximum amount of sunlight reach a solar cell. The Rice lab of chemist Andrew Barron found a simple way to etch nanoscale spikes into silicon that allows more than 99 percent of sunlight to reach the cells’ active elements, where it can be t... » read more
