China tests first practical submarine solar power plant at 10-metre depth in the open sea

In a breakthrough that could power the future of underwater operations, Chinese scientists have built and tested the world’s first submarine solar farm, successfully operating a perovskite-based photovoltaic system at a depth of 10 metres (33 feet) in the open sea. The submerged array charged batteries and powered an LED panel, proving that solar energy can be harvested even in the dim, blue-green twilight of the ocean. The achievement by a team from Yunnan University was published on September...
