Abstract

Owing to the excellent performance of zinc oxide materials under ultraviolet light, this paper proposes a process for fabricating ZnO/Au heterojunction nanostructures on the surface of silicon-based solar cells using anodic aluminum oxide as the template, ultimately resulting in a novel silicon-based solar cell with an embedded ZnO/Au nanostructure array. Through model optimization and analysis of the solar cells, it is found that compared with silicon-based solar cells with double grating nanostructures, silicon-based solar cells with surface silicon nanostructure arrays prepared by similar processes, and traditional planar silicon-based solar cells, the light absorption efficiency of the proposed solar cell structure is improved by 13.2%, 35.01%, and 63.78%, respectively; its short-circuit current density and power conversion efficiency reach 40 mA/cm2 and 20.17%, respectively. Meanwhile, this paper conducts an in-depth study on the performance enhancement mechanism, providing new insights for the fabrication of ZnO/Au heterojunction nanostructures and their applications in the field of solar cells.
