Perovskite Stability Gets a 2D Solution
Perovskite structures suffer from moisture and thermal stability issues which prevent their commercial use. This promising solution using organic cations leads to a record high PCE for 2D perovskite devices.
Thermal Camouflage: Illusion Meta-Devices
Camouflage, illusion or cloaking devices, once deeply rooted in science-fiction, can make an object appear “invisible”. A novel technique for thermal illusion meta-devices is reported.
Cloak of Inv sib ity
A true invisibility cloak would encompass an object, and manipulate light, in a manner such that it traveled around the object, rather than reflecting off it. A recent paper reports some exciting progress toward such a design.
