研究目的
To realize large-area perovskite solar cells (PSCs) with high efficiency, long lifetime, low toxicity, and device upscaling through a green solution bathing strategy.
研究成果
The GSB strategy using 2-pentanol and FACl significantly improves the performance of PSCs, achieving high efficiency and enabling large-area fabrication. This approach is a step forward towards practical application of PSCs with environment-friendly techniques.
研究不足
The study focuses on the use of 2-pentanol and FACl in the GSB process, and while it shows promising results, the scalability and long-term stability of the PSCs under various environmental conditions need further investigation.
1：Experimental Design and Method Selection:
A green solution bathing (GSB) strategy was employed using 2-pentanol as a green solvent and formamidinium chloride (FACl) as a solute to prepare perovskite films.
2：Sample Selection and Data Sources:
Mixed-cation lead mixed-halide perovskite precursor solution was used.
3：List of Experimental Equipment and Materials:
2-pentanol, FACl, ITO/SnO2 substrates, Spiro-OMeTAD, Au.
4：Experimental Procedures and Operational Workflow:
The perovskite precursor solution was spin-coated on ITO/SnO2 substrates, then immersed into the 2-pentanol solution of FACl, followed by annealing.
5：Data Analysis Methods:
SEM, XRD, UV-vis absorption spectra, PL spectroscopy, TRPL measurements, AFM, c-AFM, and PL imaging were used for characterization.
