| 제목 | Fabrication of SnS Absorber Layer by Vapor Transport Deposition and Evaluation of Thin Film Solar Cells Characteristics |
| 초록 | The broad use of photovoltaic energy as an infinite source of clean energy is still limited because of the high cost of power generation. Tin monosulfide (SnS) has been researched widely as a good candidate for earth-abundant photovoltaic absorber. SnS has a direct band with the bandgap of 1.2~1.5 eV and high optical absorption coefficient over 104 cm-1, which is nearly optimum for photovoltaic solar energy conversion. Even though SnS has many advantages, it is difficult to grow pure-phase SnS because of easy formation of secondary phases such as SnS2 and Sn2S3. In this work, SnS films were deposited by vapor transport deposition using SnS powder in a horizontal furnace. We changed pressure and temperature of SnS powders and substrates. We tried to find the optimal condition to obtain phase-pure SnS thin films. It was found that the substrate temperature and pressure influence the final phase of the deposited sulfides. Device structure of fabricated cells is glass/Mo/SnS/CdS/ZnO/AZO/Ni/Ag. More details on structural, optical, and electrical properties will be discussed in this presentation. |
