Researchers have carried out tests on solar panels placed as deep as 10 metres underwater, a development that could point toward longer-lasting power sources for subsea equipment and reduce a sole reliance on batteries, according to TradeArabia News Service.
The panels were engineered to capture blue and green wavelengths of sunlight, which pass through seawater more effectively than other parts of the light spectrum.
In a two-hour trial conducted near China’s Weizhou Islands, the technology produced 324 milliwatt-hours of electricity at a depth of 10 metres. The research, published in Joule, extends earlier work that had been limited to depths of two metres or less.
The team relied on perovskite solar cells, which can be adjusted to absorb particular wavelengths and serve as an alternative to conventional silicon cells. Laboratory testing indicated that the cells turned about 35% of available sunlight into electricity under conditions designed to replicate a 10-metre depth.
Drawing on the testing, the researchers estimate that the panels could run continuously underwater for roughly 5.5 years. Such a capability could potentially support subsea sensors, monitoring systems and other equipment.
This report provides an in-depth analysis of the Perovskite Solar Cells market in China, including market size, structure, key trends, and forecast. The study highlights demand drivers, supply constraints, and the competitive landscape across the value chain.
