研究目的
Investigating the effect of titanium tetrafluoride (TiF4) as an additive on the efficiency, stability, and scalability of perovskite solar cells (PSCs).
研究成果
The addition of TiF4 to perovskite solar cells significantly enhances their power conversion efficiency and moisture stability by passivating interfacial defects, demonstrating a promising approach for improving perovskite device performance.
研究不足
The study focuses on the passivation effect of TiF4 on perovskite interfaces but does not explore the long-term stability under various environmental conditions beyond moisture.
1：Experimental Design and Method Selection:
The study employed a one-step antisolvent spin-coating method for perovskite film preparation with TiF4 additive.
2：Sample Selection and Data Sources:
Perovskite precursor solution was prepared with specific stoichiometric ratios and TiF4 concentrations.
3：List of Experimental Equipment and Materials:
Instruments included spin-coaters, spectrophotometers, and X-ray photoelectron spectroscopy (XPS) for analysis.
4：Experimental Procedures and Operational Workflow:
The process involved spin-coating, annealing, and characterization of perovskite films with and without TiF
5：Data Analysis Methods:
Performance metrics like PCE, VOC, JSC, and FF were analyzed alongside stability tests.
