Scientists test underwater solar panels that work 10 meters beneath the waves —breakthrough perovskite tech could support self-powered marine drones

Scientists have successfully developed solar panels capable of generating power at depths of up to 10 meters beneath the ocean's surface. These panels, created by researchers from Yunnan University in China, utilize lead halide perovskite and a polymer additive to enhance their efficiency. At 10 meters down, the panels produced 324 mWh of energy per device, maintaining their functionality for up to five and a half years.

This breakthrough could pave the way for self-sustained marine energy systems and autonomous underwater devices, such as sensors and communication systems, which often require frequent maintenance and manual intervention when powered by traditional methods. Researchers note that biofouling, or the accumulation of organic matter, may pose challenges to the panels' performance and suggest regular cleaning may be necessary to ensure optimal operation.

Despite this, the findings present a promising avenue for powering underwater devices without the need for constant human intervention, potentially transforming the way we interact with the ocean and its resources.
