| 제목 | LOW TEMPERATURE, SOLUTION PROCESS FABRICATION OF PHOTODIODES USING METHYL AMMONIUM LEAD HALIDES |
| 초록 | Methyl Ammonium Lead Halides, perovskites, are the attractive light harvesting semiconducting materials, as it has high carrier mobility and high photo conversion efficiency. In addition, these materials have advantage of low temperature processing, easy to deposit, large scale processing. Furthermore, the perovskite materials are sensitive to a wide band wavelength from ultraviolet to visible range. However, the mechanism for the growth of the hybrid perovskite crystalline structure is not properly understood on the planar surfaces. In this study, the methyl ammonium lead Iodide was investigated to reveal the effects of the experimental variables such as post anneal temp, post anneal time, and lead iodide-methyl ammonium iodide composition on the growth and the morphology using in situ XRD technique and FE-SEM. Different deposition process were compared to apply perovskite films on planar substrates. Finally the perovskite films were used to fabricate the photodiodes with various structures. |
