Self-cleaning perovskite solar cell based on leek leave-like film achieves 14.2% efficiency

Scientists in Finland have built a perovskite solar cell with a bio-inspired coating that reportedly improves light transmittance while providing self-cleaning properties. The film was able to improve the device efficiency by up to 6%. A research team at Aalto University in Finland has developed a perovskite solar cell based on a "light management layer" made of a polymer material with the surface of leek leaves that can reportedly improve the device efficiency by up to 6%. The scientists explained that the bio-inspired layer has self-cleaning properties. "The films' self-cleaning can maintain ...
