Contact Between Two Perovskite Films Boosts Solar Cell Efficiency and Durability Without Added Chemicals

London, United Kingdom (SPX) Apr 23, 2026 A technique that improves the performance and stability of next-generation solar cells - without adding any chemicals or coatings - has been demonstrated by researchers from Korea University and the University of Surrey. The study, published in Nature Energy, details a method that works by placing two types of perovskite film in contact with each other. That contact alone triggers a molecular in
