研究目的
Investigating the performance of an all-perovskite photodetector with fast response.
研究成果
The study demonstrated highly photosensitive perovskite photodetectors decorated by perovskite QDs, showing high responsivity, detectivity, carrier mobility, and fast response. However, efforts are needed to reduce the electrode spacing width for efficient charge transport and to improve the device's lifetime.
研究不足
The wide electrode span lowers the performances of devices such as photocurrent-related responsivity. The short lifetime of the device remains a severe bottleneck in commercial application.
1：Experimental Design and Method Selection:
The study involved the fabrication of a photodetector using solution-processing organic-inorganic hybrid perovskite CH3NH3PbI3?xClx layer decorated with CsPbBr3 perovskite quantum dots.
2：Sample Selection and Data Sources:
The active layer was deposited via spin-coating followed by post-annealing. The sensitized layer, CsPbBr3 QDs, was spin-coated layer by layer.
3：List of Experimental Equipment and Materials:
A commercial silicon wafer with a 300-nm-thick SiO2 layer was used as the substrate. Materials included N,N-dimethylformamide (DMF), oleic acid (OA), 1-octadecene (ODE), oleylamine (OLA), PbCl2, PbBr2, and CH3NH3I.
4：3I. Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The device fabrication involved spin-coating the active layer, decorating it with CsPbBr3 QDs, and thermally evaporating source and drain electrodes.
5：Data Analysis Methods:
The performance of the photodetector was evaluated based on responsivity, detectivity, carrier mobility, and response time.
