Application of N-doped ZnO Nanorods in Heterojunction Si Solar Cells
In last few decades the study of zinc oxide (ZnO) nanoparticles established the fact that, they have wide range of high technology applications. Among all the nanoparticles ZnO nanorods have been widely used due to their ease of formation and applications. Here, nitrogen doped (N-doped) ZnO nanorods have been developed by hydrothermal method. The layer of N-doped ZnO nanorods along with crystalline silicon (c-Si) wafer forms a heterojunction Si solar cell. It has minimum reflectance and good light trapping effect. Hence, no need to use another layer for ARC. The use of this layer provides an efficiency enhancement.
