研究目的
Investigating the photovoltaic properties of Mott Insulator LaVO3 (LVO) as a potential solar energy conversion material.
研究成果
The experimental result shows that LVO perovskite materials are very effective for solution process photovoltaic. The energy band gap of LVO is found to be 3.81 eV, which is suitable for Mott type insulators ranging from ultra-violet to near infra-red (NIR) regions. These investigations could pave the path for subsequent development of LVO perovskite as photovoltaic applications.
研究不足
The study mentions constraints like lack of long-term stability and lead toxicity in perovskite solar cells, and the difficulty in finding suitable oxide materials for photovoltaic applications.
1：Experimental Design and Method Selection:
The study involved the sol–gel technique for growing LVO thin films followed by sintering under various processing conditions.
2：Sample Selection and Data Sources:
Fluorine doped Tin Oxide (FTO) coated glass substrates were used.
3：List of Experimental Equipment and Materials:
LaVO3 was purchased from TAEWON SCIENTIFIC CO., LTD., and various characterization tools like XRD Diffractometer, Raman spectroscopy, UV–visible spectroscopy, FESEM, and J–V analysis were used.
4：Experimental Procedures and Operational Workflow:
The process included cleaning FTO substrates, spin coating of sol–gel solution, heating, and characterization.
5：Data Analysis Methods:
Structural, optical, and electrical properties were analyzed to correlate material parameters with device performance.
