In this study, a high energy conversion efficient dye-sensitized solar cells (DSSC) was successfully fabricated by attaching a double anti-reflection (AR) layer which is composed of a subwavelength moth-eye structured polymethyl methacrylate (PMMA) film and a polydimethylsiloxane (PDMS) film. The efficiency is up to 6.79%. The moth-eye structured PMMA film was fabricated by using anodic aluminum oxide (AAO) template which is simple, low-cost and scalable. The nano-pattern of AAO template has been precisely reproduced onto PMMA film. The photoanode is composed of Titanium dioxide (TiO2) nanoparticles (NPs) with diameter of 25 nm deposited on the fluorine-doped tin oxide (FTO) glass substrate and the sensitizer N3. The double AR layer can effectively improve the short-circuit current density (JSC) and conversion efficiency from 14.77 to 15.79 mA/cm2 and from 6.26% to 6.79%, respectively.

Anodic Aluminum

Anodic aluminum oxide (AAO) was used as a template coupled with liquid process for synthesis of TiO2 nanorods. Immersion setting (IS) was carried out to insert a TiO2 precursor solution into AAO pore. With the calcination and NaOH treatment to remove AAO, SEM characterization revealed that TiO2 nanorods with diameter around 100-200 nm were successfully fabricated from AAO commercial templates. The synthesized nanorods mixed with commercial TiO2 nanoparticles (P-25) with a mixing ratio of 5:95 (by mass) were used as an electrode in a dye-sensitized solar cell (DSSC), The photoelectrodes made with nanorods showed a better performance than the cells used of only pristine TiO2 nanoparticles. The results from current density-voltage (J-V) characteristics of DSSCs showed that short-circuit current density (JSC), open-circuit voltage (VOC), fill factor (FF), and power conversion efficiency (PCE) are 11.78 mA/cm2, 0.72 V, 0.55, and 4.68%, respectively. Due to the effects of one-dimensional (1-D) nanostructure, the electron expressway concept was achieved in this research.

Indium nanowires with diameters approximately 300 nm have been synthesized by a hydraulic pressure technique using anodic aluminum oxide (AAO) templates. The indium melt is injected into the AAO template and solidified to form nanostructures. The nanowires are dense, continuous and uniformly run through the entire ∼60 μm thickness of the AAO template. X-ray diffraction (XRD) reveals that the nanowires are polycrystalline with a preferred orientation. SEM is performed to characterize the morphology of the nanowires.

Copper nanodisks (Cu NDs) of 50 nm were prepared on square-inch anodic aluminum oxide substrates by sputtering method. The samples were annealed at 450oC, then the walls of AAO substrates were lift off in a solution of acid phosphoric. The 2D arrays of Cu NDs were fabricated in high quality. Morphology of the substrates were observed by scanning electron microscopy. Surface plasmon resonance absorption was observed with different peaks in the range of 400-1400nm wavelengths that means the substrate is promising for SERS application. To demonstrate, we observed Raman spectrum of Rhodamine 6G using the enhancement effect of the substrate.
