Army Looks Into Laser-Powered Drones

Even as drone technology advances, power constraints limit the amount of equipment unmanned systems can carry, as well as the time they can stay in the air. Some drone systems, like the Persistent Aerial Reconnaissance and Communications drone from CyPhy Works, deliver power through a tether to keep a small drone aloft for an entire

Researchers Boost Efficiency and Stability of Optical Rectennas

The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices — and a switch to air-stable diode materials. The improvements could allow the rectennas – which convert electromagnetic fields at optical frequencies directly to electrical current – to operate low-power devices such as temperature

Ultra-Stable Perovskite Solar Cell Remains Stable for Over a Year

Perovskite solar cells promise cheaper and efficient solar energy, with enormous potential for commercialization. But even though they have been shown to achieve over 22{261f6ead6a0f3cabae584e9904bae8bd53a3c91c6c837aa2d58453541104ad2d} power-conversion efficiency, their operational stability still fails market requirements. Despite a number of proposed solutions in fabrication technology, this issue has continued to undercut whatever incremental increases in efficiency have
