New Perovskite Solar Cells Designed for Underwater Use

<p>A team led by Simin Ma at Yunnan University has developed new perovskite solar cells that are designed to function underwater. These solar cells, made from perovskites instead of traditional silicon, offer advantages such as lower production costs, flexibility, and higher efficiency in converting solar energy into electricity. However, they typically face challenges with degradation over time.</p><p>Perovskites are sensitive to moisture, which raises questions about their suitability for underwater applications. Nonetheless, these materials can be engineered to absorb different wavelengths of light. While silicon solar panels struggle to capture light in deeper waters due to absorption, the new perovskite cells are expected to generate electricity even in low-light conditions. The cooler temperatures and reduced light levels underwater may also contribute to their longevity.</p>
