Flexible and Stickable Perovskite Solar Cells

Perovskite solar cells have achieved power conversion efficiencies exceeding 25% in recent years. The specialty of flexible perovskite solar cells is that they can be fabricated onto flexible substrates, making them lightweight, flexible, and wearable. They can be attached to equipment that requires low electrical power, such as solar vests, solar recharge backpacks, flexible solar panels, drones, and boats. This work presents an approach to fabricating flexible perovskite solar cells on adhesive label (stickable-removable) substrates. Different counter electrodes have been compared. The concept of utilizing adhesive label substrates in fabricating flexible perovskite solar cells, as well as a pathway for creating dependable power sources for stickable-removable electronic devices, will be presented.
