【 摘 要 】

tsTrace amounts of long-chain gemini surfactants are essential for blade-coating of high-quality perovskite films, enabling a 17.05% efficient full printed carbon-based module (50 cm2 active area).Only when the surfactant chain is over a critical length will the gemini surfactant be effective for blade-coating of perovskite films.The surfactants increase the capillary number of perovskite precursor solution, reduce the local disturbance and combat inhomogeneous solidification during blade coating, thus allowing high-quality perovskite films to be formed.
