研究目的
Investigating the photovoltaic effect in BaTiO3 thin film for potential photovoltaic applications.
研究成果
The BaTiO3 thin film annealed at 600°C showed significant photovoltaic effect with a high power conversion efficiency of 1.25%, suggesting its potential for future photovoltaic applications.
研究不足
The presence of impurity phases at lower annealing temperatures and the need for higher annealing temperatures to achieve pure phase BaTiO3 may limit the application scope.
1:Experimental Design and Method Selection:
BaTiO3 thin films were grown on n-type silicon (100) substrates using high vacuum magnetron sputtering and annealed at different temperatures.
2:Sample Selection and Data Sources:
Samples were annealed at 400, 500, and 600°C under vacuum conditions.
3:List of Experimental Equipment and Materials:
Used radio-frequency magnetron sputtering, SEM for morphology, EDX for chemical analysis, XRD for crystal structure, and Keithley 2400 for I-V curves.
4:Experimental Procedures and Operational Workflow:
Films were deposited and annealed, then characterized for structure, morphology, and photovoltaic properties.
5:Data Analysis Methods:
Analyzed using XRD patterns, SEM images, EDX data, and I-V characteristics under dark and light conditions.
