| Summary: | 碩士 === 國立臺南大學 === 綠色能源科技學系碩士班 === 107 === The research on the photoelectric properties of perovskite materials are rapidly progressing, but perovskite materials are unstable in the atmosphere, so most of the research is done in an inert environment. In this study, colloidal perovskite nanoparticles were synthesized in the atmosphere, and self-assemble CH3NH3PbBr3 and CH3NH3PbI3 perovskite nanocrystalline films by chemical bath deposition, the whole process was completed in non-polar solvents. Our proposed synthesis method different from the high temperature mechanism of the thermal injection method. Finally, the LED elements of CH3NH3PbBr3 and CH3NH3PbI3 with glass/ITO/PEDOT:PSS/CH3NH3PbBr3 or CH3NH3PbI3 /TPBI /LiF /Al structure have a maximum brightness of about 200 and 16.8 cd/m2; the current efficiency is 0.205 cd/A, 0.004 cd/A; electroluminescence wavelength is 520, 688 nm, respectively.
