The lighter wand for your gas BBQ, a submarine’s sonar device and the ultrasound machine at your doctor’s office all rely on piezoelectric materials, which turn mechanical stress into electrical energy, and vice versa.
Designing a 3-D printed structure is hard enough when the product is inches or feet in size.
Researchers at the Department of Energy’s Oak Ridge National Laboratory have found a potential path to further improve solar cell efficiency by understanding the competition among halogen atoms during the synthesis of sunlight-absorbing crystals.
Two-dimensional electronic devices could inch closer to their ultimate promise of low power, high efficiency and mechanical flexibility with a processing technique developed at the Department of Energy’s Oak Ridge National Laboratory.
