Power/Performance Bits: July 3


Graphene foam devices Scientists at Rice University developed a method for building conductive, three-dimensional objects out of graphene foam, which they say could offer new possibilities for energy storage and flexible electronic sensor applications. The same lab initially created laser-induced graphene, or LIG, in 2014. The process involves heating inexpensive polyimide plastic sheets wi... » read more

Next-era transistors engage diamonds To advance the development of more robust and energy-efficient electronics, materials scientists from Japan’s National Institute for Materials Sciences have developed a new diamond transistor fabrication process. To address the challenges of silicon, Jiangwei Liu and the team have recently described new work developing diamond-based transistors. “Sil... » read more

Power/Performance Bits: Jan. 20


Boosting silicon solar cells According to Stanford researchers, stacking crystalline perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell. The researchers reminded that silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25 percent for 15 years. One inexpensive wa... » read more
