| Popis: | 104 In this thesis, we have successfully fabricated high quality perovskite film by solution-process assisted with flowing nitrogen. The perovskite films exhibit good crystallinity, high coverage, smooth surface morphology, and efficient light absorption, characterized by X-Ray diffraction (XRD), UV-VIS spectrophotometry (UV-VIS), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The current density, open circuit voltage, fill factor and photoelectric conversion efficiency of the solar cell realized by the perovskite film were 25.64 mA/cm2, 0.84 V, 0.67, and 14.48 %, respectively. The slow growing technique is also implemented in the electron transporting materials to enhance the efficiency of solar cell. The coverage of the electron transporting material has been increased by the slow growing process which analysis by atomic force microscopy. The fill factor and photoelectric conversion efficiency of the device was enhanced from 0.66 to 0.73 and 14.08 % to 17.84 %, respectively. |
