研究目的
Investigating the effects of oxygen plasma treatment on Spiro-OMeTAD for enhancing the performance of perovskite solar cells.
研究成果
Oxygen plasma treatment of Spiro-OMeTAD significantly enhances the performance of perovskite solar cells, achieving an efficiency above 15%. The treatment improves the match of homo energy levels between perovskite and Spiro-OMeTAD, facilitating better hole carrier transfer. However, excessive treatment time can degrade the MAPbI3 layer, reducing cell performance.
研究不足
The study is limited by the sensitivity of perovskite to moisture and the potential degradation of MAPbI3 under prolonged oxygen plasma treatment.
1：Experimental Design and Method Selection:
The study involved the fabrication of perovskite solar cells with Spiro-OMeTAD as the hole transport material, followed by oxygen plasma treatment to enhance its performance.
2：Sample Selection and Data Sources:
FTO substrates were used, cleaned, and treated with oxygen plasma. TiO2 blocking and mesoporous layers were prepared, followed by MAPbI3 film deposition.
3：List of Experimental Equipment and Materials:
Equipment included a COVANCE-2MPR plasma processing system, UV–vis-NIR spectrometer, Fluorescence Spectrometer, and others. Materials included Spiro-MeOTAD, titanium diisopropoxidebis, and others.
4：Experimental Procedures and Operational Workflow:
The process involved substrate cleaning, layer deposition, plasma treatment, and characterization.
5：Data Analysis Methods:
XRD, UV–vis absorption, PL, EQE, and J-V curves were analyzed to evaluate the solar cell performance.
