In recent years, it has become possible to refuel unmanned drones in mid-air via laser refuelling systems that deliver energy from a station on the ground. The key to this system is an array of photovoltaic cells that are explicitly calibrated to an infrared laser’s wavelength.

Perovskite solar cells show unparalleled efficiency growth, but stability issues persist. Hyperspectral imaging aids in understanding material inhomogeneities.
Wearable optics come in many different forms, from the low-tech aesthetics by integrating optical fibers with clothing, to newly created advanced optical sensors and creating high-tech applications, such as integrating advanced optical components into augmented reality (AR) headsets.
