研究目的
Investigating the synthesis of TiO2 nanoparticles using sol-gel-hydrothermal colloidal route in two different apparatus for application in dye-sensitized solar cells (DSSCs).
研究成果
The autoclave method produces high quality TiO2 nanoparticles (TiO2-W) which are superior to both the stainless steel chamber synthesized TiO2-B and commercial TiO2-C nanoparticles. TiO2-W exhibits better power conversion efficiency in DSSC as compared to TiO2-B.
研究不足
The study is limited to the synthesis and characterization of TiO2 nanoparticles and their application in DSSCs. The comparison is made only between two synthesis methods and commercial TiO2 nanoparticles.
1：Experimental Design and Method Selection:
TiO2 nanoparticles were synthesized using sol-gel-hydrothermal colloidal route in two different apparatus (stainless steel and autoclave).
2：Sample Selection and Data Sources:
The synthesized TiO2 nanoparticles (TiO2-B and TiO2-W) were compared with commercial TiO2 nanoparticles (TiO2-C).
3：List of Experimental Equipment and Materials:
Stainless steel chamber, autoclave, SEM, XRD, photoluminescence spectrophotometer.
4：Experimental Procedures and Operational Workflow:
Synthesis of TiO2 nanoparticles, characterization using SEM, XRD, and photoluminescence spectrophotometer, and application in DSSCs.
5：Data Analysis Methods:
Crystallite size was measured using Debye–Scherrer’s formula, PL quenching rate was calculated, and photovoltaic performance was analyzed.
