Observational analysis improved power conversion efficiency to 11.59% in tin halide perovskite solar cells, suggesting enhanced stability through pentafluorobenzoic acid.
Key Points
Power conversion efficiency improved to 11.59%, showcasing the effectiveness of pentafluorobenzoic acid in enhancing tin halide perovskite solar cells.
After 1500 hours in a nitrogen glovebox, the device retained 88.00% of its initial power conversion efficiency, indicating significant stability.
The crystallization process was regulated by pentafluorobenzoic acid, reducing lattice stress and avoiding defect-induced recombination centers.
The addition of pentafluorobenzoic acid improved the hydrophobicity of the film, mitigating water and oxygen invasion.
