Researchers at Yunnan University's team led by Ma Simin have developed a perovskite solar cell capable of generating electricity underwater, addressing a longstanding limitation of conventional silicon-based solar technology.1 The perovskite material overcomes the optical barrier that water creates for silicon cells by enabling tunable absorption across different light wavelengths, allowing properly designed perovskite cells to produce power even in deep ocean environments.1
Perovskite solar cells offer several advantages over their silicon counterparts, including lower cost, diverse structural configurations, and higher conversion efficiency.1 Although perovskite materials are particularly sensitive to moisture and prone to degradation, the team's design addresses this technical challenge.1 Notably, the low-light and low-temperature conditions found underwater actually extend the battery's operational lifespan rather than diminishing it.1
