Underwater Solar Cells Reportedly Charge Batteries at 10 Meters
An underwater solar module reportedly charged a battery at a depth of ten meters. The test extends beyond the depths of two meters or less that dominated earlier demonstrations.

Generating 324 mWh at a depth of ten meters
A Yunnan University team reportedly deployed 115 cm² perovskite solar-cell modules by remotely operated robots at depths of two, six, and 10 meters. At 10 meters, the article says the cells generated 324 mWh and charged lithium-ion batteries sufficiently to light an LED sign.
Earlier reported underwater-solar-cell studies focused on very shallow water, at depths of two meters or less.
The reported field test extended operation from prior shallow-water demonstrations to 10 meters underwater, where the modules charged lithium-ion batteries.
Sunlight is substantially reduced underwater. If the reported field result holds, it demonstrates solar modules operating at a depth deeper than the shallow-water tests described in the article and may broaden options for powering stationary underwater equipment.
