Power/Performance Bits: Sept. 18


Etching photovoltaics Researchers at Michigan Technological University and Aalto University found a way to reduce production costs of black silicon solar cells by more than 10%. The first prototype modules have been manufactured on an industrial production line. Typically, the silicon used for solar cells is etched to reduce reflected light, although some light is still lost. Nano-texturing... » read more

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
