Synergistic Cosensitization and Redox-Triggered Interfacial Engineering for Efficient and Durable Solar Cells
, generating free radicals and enhancing intramolecular charge transfer. Importantly, the redox byproduct 2-iodobenzoic acid (IA) plays a critical role in suppressing interfacial recombination and passivation by coordinating with lithium ion and forming halogen-bonded complexes with electrolyte additives. The synergistic effects of cosensitization and the IBA additive in the electrolyte yield a cosensitized DSC with a PCE of 12.84%, featuring excellent operational stability under indoor light soaking for 1000 h. Moreover, the control device achieves an efficiency of 25.81% when tested under indoor light (4500 lx) illumination.
