🌊☀️ SOLAR POWER — 10 METERS UNDER THE SEA!

Chinese researchers have successfully tested a perovskite solar power system 10 meters (33 feet) beneath the surface of the open sea.

Researchers from Yunnan University used the system to charge lithium-ion batteries and power an LED panel underwater.

Unlike conventional silicon solar cells, these new perovskite solar cells are designed to capture blue-green light, which can pe*****te seawater more effectively at greater depths.

🔬 A larger test module achieved an impressive 29.4% efficiency under simulated underwater conditions.

The researchers also developed a multilayer waterproof structure to protect the cells from seawater corrosion, pressure, and moisture. After 1,000 hours of immersion in simulated seawater, the cells retained 99.58% of their initial performance.

🌊 In a real-world test in the South China Sea, the system generated 324 mWh of electricity in just two hours at a depth of 10 meters — enough to recharge batteries and power an LED panel.

🚀 What could this mean for the future?

This technology could potentially provide continuous power for underwater sensors, cameras, communication equipment, and other remote marine systems — opening up a new frontier for solar energy.

☀️ Solar energy is no longer limited to the surface. The future of clean energy could be underwater.

☀️ THE WORLD IS GOING SOLAR — AND SRI LANKA IS MOVING WITH IT.

Solar PV has become one of the fastest-growing sources of new electricity worldwide. By the end of 2024, global solar PV capacity reached 1,865 GW, with a record 452 GW added in a single year.

Sri Lanka is also making significant progress. In 2024, rooftop solar reached 1,141 MW across more than 73,000 connections, while solar generated more than 1,100 GWh of electricity during the year.

🇱🇰 We may be a small island, but our solar potential is enormous.

The journey has only just begun.
