# Laser Receiver Advances Civil Aviation University of China Unveiled Its Perovskite Laser Cell By Adam Harrie | Written with AI assistance | Published 2026-08-14 | Updated 2026-08-21 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/Civil-Aviation References: [newatlas](https://newatlas.com/drones/improved-receiver-laser-powered-drones/)  Researchers at the Civil Aviation University of China developed a [lightweight drone receiver](https://www.trendhunter.com/trends/lace-research-quadcopter) designed to harvest energy from a ground-based laser. The system combines a [perovskite laser cell](https://www.trendhunter.com/trends/integrated-laser-system) with a thermoelectric generator to convert both laser energy and heat into onboard electricity. The design incorporates nanocrystals that act as a thermal barrier, helping limit heat transfer as the receiver warms during operation. Researchers mounted the unit beneath the wing of a stationary drone and added air channels to improve cooling, while propeller airflow helped lower temperatures during testing. The receiver converted 38.49% of incoming laser energy into electricity and generated enough power to spin the drone’s propeller. The next step is outdoor flight testing to evaluate performance over distance and at altitude. The research advances efforts to make [laser-based airborne charging](https://www.trendhunter.com/trends/wireless-power1) more practical for longer-duration drone operations.
