| 초록 |
Colloidal quantum dot solar cell is one of the attractive next generation solar cell based on low-cost, simple solution process. However, most of solar cell include Pb element, which has been an obstacle for commercialization. InAs, one of the eco-friendly materials, has tunable band gap from visible to near infra-red with large bohr radius. Also level of energy is readily shifted depending on surface ligands. Here, we introduced continuous injection so that synthesized the quantum dot with desirable size. Then, we controled the surface ligands with two-step treatment for the preferred energy level. Lastly, we applied it to solar cell, and demonstrated high-efficient, stable properties. |
