GoKawiilChinese researchers test perovskite solar panels 10 meters underwater
Scientists near Weizhou Island, publishing in the journal Joule, generated electricity from sunlight at a depth of about 33 feet using perovskite-based solar cells tuned to capture blue and green light that penetrates seawater. The two-hour simulated test produced 324 milliwatt-hours and reached a peak power conversion efficiency near 35 percent, according to the study led by Yunnan University's Wen-Hua Zhang.
GoKawiil's interpretation of the reporting above, not reported fact.
The reported efficiency figure would edge past the Shockley-Queisser limit that has long capped theoretical silicon solar cell performance, suggesting perovskite materials could open new frontiers for photovoltaics in underwater or low-light environments. However, the results came from simulated conditions and a brief test window, so real-world viability and scalability remain unproven until independently replicated.
- Perovskite solar cells generated electricity at 10 meters underwater near Weizhou Island, China.
- Peak power conversion efficiency reached nearly 35 percent in simulated testing, per the study in Joule.
- The test lasted only two hours and produced modest power, meaning further validation is needed before real-world use.
