研究目的
Investigating the fabrication and characterization of organic-inorganic hybrid perovskite CH3NH3PbI3 based metal-semiconductor-metal photodetector for efficient light signal to electric signal conversion.
研究成果
The organic-inorganic hybrid perovskite CH3NH3PbI3 thin film-based MSM photodetector demonstrates promising performance with a responsivity of 73.683 μA/W under solar spectrum illumination, indicating its potential for low-cost, high-efficiency photodetection applications.
研究不足
The study is limited by the ambient air conditions during annealing which may affect the perovskite film quality. The responsivity values, while higher than some reported, may still be improved with optimization of film thickness and electrode materials.
1：Experimental Design and Method Selection:
The study involves the synthesis of CH3NH3PbI3 via the sol-gel chemical route and its characterization using XRD, HRSEM, and photoluminescence. A metal-semiconductor-metal (MSM) photodetector is fabricated using the synthesized perovskite.
2：Sample Selection and Data Sources:
The materials used include methylammonium iodide (CH3NH3I) and lead iodide (PbI2) in dimethylformamide (DMF) solution. Glass substrates are used for film deposition.
3：List of Experimental Equipment and Materials:
Equipment includes XRD (Model no. XDMAX, PC-20 18kW Cu rotating anode, RIGAKU, Japan), HRSEM (Model: Nova Nano SEM 450), photoluminescence spectrometer (FLS 980 from Edinburgh Instruments, UK), and semiconductor parameter analyzer (B1500A from Keysight, USA).
4：Experimental Procedures and Operational Workflow:
The perovskite solution is spin-coated on cleaned glass substrates, annealed, and then metal electrodes are deposited. The device is characterized under dark and illuminated conditions.
5：Data Analysis Methods:
The performance of the photodetector is evaluated based on responsivity calculated from photocurrent and dark current measurements.
