A new solar cell could generate electricity underwater

Researchers led by Simin Ma at Yunnan University have developed a novel perovskite-based solar cell designed to function effectively underwater. While perovskite materials are typically known for their susceptibility to moisture-induced degradation, this team has leveraged the material's unique ability to be tuned to specific light wavelengths. Since water filters out the spectrum typically absorbed by traditional silicon solar panels, these perovskite cells are engineered to capture the light that penetrates deeper into the ocean. Furthermore, the researchers suggest that the cooler temperatures and lower light intensity found in deep-water environments may actually extend the operational lifespan of these cells. This innovation represents a significant step forward in energy harvesting technology, potentially opening new possibilities for powering underwater equipment and autonomous systems without the need for traditional battery replacements or surface-level energy sources.
