Abstract
Plasmonic nanostructures have been demonstrated for their application in thin film solar cells to enhance absorption. Of particular concern is the novel design, enabling the broadband absorption enhancement. Here, we proposed and implemented a periodic corrugated Au nanomesh for broadband light absorption enhancement. By combining plasmon treatment of pre-stretched substrate and nanosphere lithography, the Au nanomesh on the nanocorrugation with different period has been realized. Compared to the planar nanomesh, the periodic corrugated nanomesh exhibits observable absorption enhancement at broad wavelength range, especially from 700[Formula: see text]nm to 1000[Formula: see text]nm, which is of significance in bring solar energy up to more utilization due to poor absorption of thin film solar cells at the near-infrared band. The enhancement attributes to the spatially geometry deformation of nanomesh supported more plasmonic resonance at the different adjacent frequency. Also, the absorption enhancement is relative to the period of corrugation, which caused by the variation of geometry deformation amplitude of nanomesh. This periodic corrugated metallic nanomesh provides an alternative nanostructured electrode to broadband absorption enhancement for thin film solar cell application.
