Controlled synthesis of ZnO nanocrystals with various morphologies by capping molecules assisted hydrothermal process and their application in the dye sensitized solar cells |
| 초록 |
The fabrication of nanomaterials with a controllable size and shape is of great scientific and technological interest, mainly due to the significant influences of size and shape on their properties. Recently, ZnO has shown a wide range of technological and practical applications, is a potentially useful semiconductor with a direct band gap of 3.37 eV which is very close to the band gap of TiO2. A hydrothermal treatment could be the most simple and effective way to prepare sufficiently well-defined crystalline shape and size materials at low temperatures. In this paper, we synthesized the various morphologies of nano-flowers, nanoballs and nanoplates ZnO by capping molecules assisted hydrothermal process at 1600C. Generally, various morphologies of zinc oxide have potential advantage in the sense of charge transport improvement, recombination and minimize the grain boundaries in between the interfaces. Dye sensitized solar cell fabricated from synthesized ZnO nanomaterials, and the maximum overall conversion efficiency of 2.61% obtained with high ISC of 12.26 mA/cm2. |
