Current solar panels are rigid, hard to store in large numbers and integrate into everyday appliances like phones, windows, or vehicles. To be integrated into them, solar cells need to be foldable, to bend repeatedly without breaking within a very small radius while maintaining integrity and other desirable properties. A thin, flexible, transparent, and resilient conductor material is needed. This isn’t possible with conventional ultra-thin glass substrates and metal oxide transparent conductors, able to be made flexible but not fully foldable. Scientists have an answer: single-walled carbon nanotube (SWNT) films, owing to their high transparency and mechanical resilience. They also introduced small impurities into the SWNT-PI nanocomposite layer, increasing the amount of charge that can be generated for a given amount of current.
