Power/Performance Bits: June 28


Mimicking roses for solar Scientists from the Karlsruhe Institute of Technology (KIT) and the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) reproduced the epidermal cells of rose petals and integrated the transparent replicas into an organic solar cell, with an efficiency gain of 12%. The epidermis of rose petals consists of a disorganized arrangement of densely p... » read more

Power/Performance Bits: April 14


Elastic energy harvesting Researchers from the Korea Advanced Institute of Science and Technology (KAIST) and Seoul National University collaborated to develop a hyper-stretchable elastic-composite energy harvesting device. Their stretchable piezoelectric generator can harvest mechanical energy to produce a ~4V power output with around 250% elasticity and a durability over 104 cycles. The... » read more

Black phosphorus photodetectors Phosphorus, a highly reactive element commonly found in match heads, tracer bullets, and fertilizers, can be turned into a stable crystalline form known as black phosphorus. In a new study, researchers from the University of Minnesota used an ultrathin black phosphorus film 20 atoms thick to demonstrate high-speed data communication on nanoscale optical circui... » read more
