研究目的
Investigating the application of poly(4-vinylpyridine) (PVP) interlayer and quaternary semiconductor Cu2MSnS4 (M = Co2+, Ni2+, Zn2+) nanostructure particles as hole transport materials in perovskite solar cells to improve their stability and performance.
研究成果
The incorporation of a PVP interlayer and CMTS nanostructure particles as HTM in perovskite solar cells significantly improves their stability and photovoltaic performance, achieving a PCE of 13.57%, Voc of 1.03 V, and FF of 70.64%. The devices also demonstrated low hysteresis and retained 97% of their initial efficiency after 30 days under ambient conditions.
研究不足
The study focuses on the stability and performance enhancement of PSCs using PVP and CMTS nanostructure particles but does not explore the scalability of the fabrication process or the long-term stability under varying environmental conditions beyond 30 days.
1：Experimental Design and Method Selection:
The study involved the fabrication of perovskite solar cells in n-i-p configuration using a solution-based process for applying a PVP interlayer and CMTS nanostructure particles as HTM.
2：Sample Selection and Data Sources:
Fluorine-doped tin oxide (FTO) glasses were used as substrates. The perovskite layers were deposited by vapor-assisted solution deposition technique.
3：List of Experimental Equipment and Materials:
Materials included FTO glasses, various chemicals for synthesis, and equipment like FESEM, UV-Vis spectrometer, and solar simulator for characterization.
4：Experimental Procedures and Operational Workflow:
The process involved cleaning FTO glasses, depositing compact and mesoporous TiO2 layers, applying perovskite layers, and finally spin-coating PVP and CMTS solutions.
5：Data Analysis Methods:
The performance of the solar cells was analyzed using J-V curves, PL spectra, absorption spectra, and EIS.
