Power/Performance Bits: Sept. 19


Healing perovskites A team from the University of Cambridge, MIT, University of Oxford, University of Bath, and Delft University of Technology discovered a way to heal defects in perovskite solar cells by exposing them to light and just the right amount of humidity. While perovskites show promise for low-cost, efficient photovoltaics, tiny defects in the crystalline structure, called traps,... » read more

Power/Performance Bits: Nov. 1


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

Manufacturing Bits: Aug. 16


Safer drinking water Two-dimensional materials are gaining steam in the R&D labs. 2D materials include graphene, boron nitride (BN) and the transition-metal dichalcogenides (TMDs). These materials could one day enable future field-effect transistors (FETs). One TMD, molybdenum disulfide (MoS2), is also generating interest in other fields. Molybdenum disulfide consists of two elements--moly... » read more
