| 제목 | Patterned Double Transparent Conductive Oxide Layers for Effective Light Manipulation |
| 초록 | Two different transparent conductive oxide (TCO) materials formed of Al-doped ZnO (AZO) and Indium-tin-oxide (ITO) were applied for double TCO layers. While ITO provides excellent electrical conductivity, AZO has good optical transparency. Multilayer TCO structures have a greater potential than does a single layer TCO film, with useful aspects such as higher optical transmittance, lower resistance and a tunable work function. Photoelectric devices were fabricated by depositing three-different types of TCO films on an n-Si substrate. The AZO-coated junction (AZO/n-Si) provided higher current values compared to those of the ITO-coated junction (ITO/n-Si). An enhanced current profile was achieved from the double TCO film junctions (ITO/AZO/n-Si). Under light illumination, the single AZO-coated device provided the highest response. A 33.7 ratio of photocurrent to dark current was achieved. |
