研究目的
To improve the efficiency of single walled carbon nanotubes and n-type silicon (SWCNTs-n-type-Si) based solar cells using molybdenum disulfide (MoS2).
研究成果
The hybrid MoS2/SWCNTs-n-Si-solar cells showed an approximate 49% increment in power conversion efficiency compared to CNT only films, indicating their potential as efficient materials for photovoltaic solar cells.
研究不足
The study does not address the long-term stability and durability of the hybrid MoS2/SWCNTs-n-type-Si solar cells under various environmental conditions.
1：Experimental Design and Method Selection:
Different hybrid MoS2/SWCNTs-n-type-Si films were fabricated and optimized for the best performing cell.
2：Sample Selection and Data Sources:
SWCNT and MoS2 dispersions were used, with n-type Si wafer as a substrate.
3：List of Experimental Equipment and Materials:
Scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman spectroscopy, and ultraviolet–visible (UV–Vis) spectroscopy were used for characterization.
4：Experimental Procedures and Operational Workflow:
The films were tested for surface morphology, topography, and elemental characteristics.
5：Data Analysis Methods:
The efficiency of the solar cells was measured and compared with and without MoS2.
