Quick Summary

Scientists in China have conducted a world-first experiment by testing a practical submarine solar power plant at a depth of 10 meters in open sea. Using lead halide perovskite solar cells, they successfully charged batteries and powered an LED panel, demonstrating that solar energy can be harvested even in the relatively low light conditions under water.

Story summary

China has conducted what it claims to be a world-first experiment by testing a practical submarine solar power plant at a depth of 10 metres in open sea. Using lead halide perovskite solar cells, scientists successfully charged batteries and powered an LED panel under these conditions, demonstrating the potential for harvesting solar energy even in dim underwater environments characterized by blue-green twilight. This breakthrough could have significant implications for future marine renewable energy applications and undersea technology development.
