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

Scientists from Yunnan University have successfully tested the world's first submarine solar power plant in the open sea at a depth of 10 meters. This perovskite-based photovoltaic system demonstrated the ability to harvest solar energy in underwater conditions, charging batteries and powering an LED panel. Published on September 11 in the journal Joule, this achievement addresses the challenge of sunlight fading rapidly underwater and the limitations of conventional silicon solar cells in the remaining spectrum. The development signifies a potential advancement for future underwater operations by proving the viability of solar power in submerged environments.
