Underwater Solar Cells Breakthrough

A team of researchers at Yunnan University has developed a new type of solar cell that can generate electricity underwater. The perovskite solar cells, led by Simin Ma, are designed to work in the deep blue sea, where traditional silicon solar panels are ineffective. Unlike silicon cells, perovskites can be made cheaply and take interesting forms, such as thin, flexible, and transparent films. However, they tend to degrade quickly, especially in the presence of moisture. But the researchers have found a way to tune the materials to work with different wavelengths of light, making them suitable for underwater use. The lower light levels and cooler temperatures in the deep sea are actually beneficial for the perovskite cells, potentially extending their lifespan. This breakthrough could have significant implications for underwater energy harvesting and exploration.
