US team claims stability record for 16.19%-efficient 2D/3D tin perovskite solar cell

AI Summary

US researchers have developed a 2D/3D tin perovskite solar cell with a record efficiency of 16.19%, utilizing a chlorinated spacer to improve crystallinity and stability. The lead-free device maintained 95% of its initial efficiency after 1,600 hours under dry conditions and 80% after 1,000 hours under illumination at 55°C, marking significant progress in solar cell stability.

US researchers developed a 2D/3D lead-free tin perovskite solar cell using a chlorinated spacer, achieving 16.19% efficiency while improving crystallinity and resistance to oxygen and moisture. The device retained 95% of its initial efficiency after more than 1,600 hours in dry air and 80% after 1,000 hours under continuous illumination at 55 C.
