Underwater Perovskite Solar Cells Power Batteries in Two-Hour Deep-Sea Test
Researchers demonstrated that perovskite solar panels can charge lithium-ion batteries during a two-hour dive near the Weizhou Islands.
In a field trial off the Weizhou Islands, perovskite solar cells were attached to an underwater robot and generated enough electricity to recharge lithium-ion batteries in just two hours. The panels are tuned to capture blue-to-orange wavelengths that travel farthest in seawater and showed minimal wear in lab tests. Scientists estimate the system could run continuously at that depth for about 5.5 years, opening possibilities for long-term power of submerged sensors and cameras.
Why it matters
It shows a viable way to power long-term underwater equipment without relying on batteries or cables.
