碩士 === 中原大學 === 奈米科技碩士學位學程 === 105 === Perovskites have attracted considerable attentions in these years.Methylammonium lead halide has been used for photovoltaics because of their excellent optoelectronic properties, cheap row materials and low temperature fabrication processes. In this work, we demonstrate the realization of crystalline thin film based on CH3NH3PbI3 and CH3NH3PbBr3. The morphology of these films were inspected by an optical microscope and a scanningelectron microscope. Current-voltage curves were obtained, which were used to derive the density of trap state.
