| Summary: | 碩士 === 國立交通大學 === 光電工程研究所 === 105 === From SEM images of perovskite, we show the morphologies and crystal structures of three fabrication and the enhancement of Solvent Engineering, Two Step and LPCVD with TiO2 layer.The absorption of three fabrication becomes higher and the peak of PL is overlapped at 750 nm when inserting the TiO2 layer.The exciton lifetime of perovskite is influenced by the wavelength dependence and power dependence when inserting the mesoporous TiO2 layer. Even more, the influence of the stability and different crystal arrangement shown from the S-polarized and P-polarized orientation.The carrier lifetime of three fabrication indicates different carrier lifetime, it corresponds to the crystallization of Solvent Engineering and LPCVD are enhanced by the mesoporous TiO2 layer in the orientation of parallel to the substrate.
