Novel device harnesses shadows to generate electricity
Shadows are often associated with darkness and uncertainty. Now, researchers from the National University of Singapore (NUS) are giving shadows a positive spin by demonstrating a way to harness this common but often overlooked optical effect to generate electricity. This novel concept opens up new approaches in generating green energy under indoor lighting conditions to power … [Read more...] about Novel device harnesses shadows to generate electricity
3D-printed system speeds up solar cell testing from hours to minutes
Tests on new designs for next-gen solar cells can now be done in hours instead of days thanks to a new system built by scientists at Australia's Monash University, incorporating 3D-printed key components. The machine can analyse 16 sample perovskite-based solar cells simultaneously, in parallel, dramatically speeding up the process. The invention means that the performance and … [Read more...] about 3D-printed system speeds up solar cell testing from hours to minutes
Highly efficient charge-to-spin interconversion in graphene heterostructures
KAIST physicists described a route to design the energy-efficient generation, manipulation and detection of spin currents using nonmagnetic two-dimensional materials. The research team, led by Professor Sungjae Cho, observed highly efficient charge-to-spin interconversion via the gate-tunable Rashba-Edelstien effect (REE) in graphene heterostructures. This research paves the … [Read more...] about Highly efficient charge-to-spin interconversion in graphene heterostructures
