Chinese scientists test underwater solar panels at ten meters depth
Researchers from Yunnan University in China have tested new perovskite solar panels that function effectively up to ten meters beneath the surface of the South China Sea.
New technology powers deep sea devices
A scientific paper published in the Joule periodical details how these panels capture energy at significant depths. The cells utilize lead halide perovskite combined with a specific polymer additive to improve performance. This combination allows the system to collect enough electricity to charge lithium-ion batteries within two hours.
Expected lifespan supports long missions
Each unit is designed to operate continuously for approximately five and a half years without failure. Scientists note that powering underwater equipment has historically been difficult when devices remain submerged for extended periods. This innovation offers a solution for research vessels and autonomous drones operating far below the waves.
Study published in major journal
The team presented their findings alongside a press release explaining the technical advances of the new cells. Wen-Hua Zhang from Yunnan University stated that very few studies have previously reported on unpowered underwater operations. The research highlights a practical method to keep exploration technology ready for action without external power sources.
