GoKawiilChinese researchers build perovskite solar cells that work underwater for years
A team of Chinese scientists modified perovskite solar cells to survive and function while submerged several meters below the ocean surface. By altering the perovskite's chemical composition, adding a water-repelling coating, and using larger crystal structures, they created cells resistant to seawater degradation that still efficiently capture dim, filtered sunlight.
GoKawiil's interpretation of the reporting above, not reported fact.
Underwater solar power could open new energy options for submerged sensors, aquaculture equipment, and ocean research stations that currently rely on batteries or cables. The reported efficiency and multi-year durability suggest perovskite technology may be maturing beyond its historical vulnerability to moisture, a key barrier to commercial deployment.
- Modified perovskite cells converted about 35% of dim underwater light into electricity at simulated 10-meter depth.
- A water-repelling coating and larger crystal structures helped the cells resist seawater-related degradation.
- Lab tests suggest the panels could retain most of their efficiency for over five years underwater.
