“…The experimental realization of such systems where NAA thin films act as lighttrapping and anti-reflection layers also showed an increase in the short-circuit current density and in the PCE, although at a lower level than that previously predicted by simulations. [164] This improvement was found to be dependent on the NAA lattice period, thickness, and nanopore diameter, where further developments were foreseen by the authors. Enhanced light absorption was also observed for integrated systems based on nanoparticles-infiltrated NAA.…”

“…Their results show that NAA films can effectively passivate p ‐type silicon wafers to a level similar to PECVD or ALD thin film stacks, reaching interface state and fixed charge densities of 1 × 10 10 cm −2 eV −1 and 2 × 10 11 cm −2 , respectively. Qin et al [ 162,163 ] and Wu et al [ 164 ] have investigated the integration of NAA structures into Si solar cells for enhanced light absorption. Preliminary simulation results [ 162,163 ] showed a potential increase of ≈23% in light absorption in the wavelength range 280–1100 nm when using NAA as a light trapping layer, whereas the solar cell's short‐circuit current density was found to increase up to 131% when a double trap NAA system is used.…”

Nanoporous anodic alumina (NAA) fabricated by anodization of aluminum is a versatile platform material with tailorable geometric, optical, and chemical features for specific light‐based technologies and applications. Recent advances in anodization technology have enabled a new generation of NAA‐based photonic crystals (PCs)—periodic dielectric nanoporous structures that selectively allow, forbid, and confine the flow of incoming electromagnetic waves of specific wavelengths across their structure. NAA–PCs provide exciting new opportunities to engineer light–matter interactions with versatility across the broad spectrum, from UV to IR. But despite these fundamental advances, demonstrations of sunlight‐harvesting technologies based on NAA–PCs are still limited. Herein, an up‐to‐date summary of recent advances in NAA–PC technology is provided, and proof‐of‐concept demonstrations and future pathways to propel this versatile platform material across sunlight‐harvesting technologies such as photocatalysis, photoelectrocatalysis, photothermal energy conversion, and solar cells are discussed.

“…The solar-selective absorbing coating films should have efficient solar photothermal conversion and thus must have high solar absorptivity and low thermal emissivity, especially at high temperatures. (1,2) A spectrally selective surface should capture the maximum solar energy in the high-intensity visible and near-IR spectral regions. Minimizing the primary reflection loss at the front surface of solar thermal layers has always been a key challenge in improving power conversion efficiency.…”

Using aluminum alloy 6061-T6 as the substrate and sulfuric acid (0.3 M) anodizing technology, we formed nanoporous anodic aluminum oxide (NPAAO) films for solar absorption and photothermal sensor applications in a medium temperature range. We found that the diameter and thickness of aluminum oxide increased with increasing applied anodic voltage. The increase in the applied anodic voltage, which increased the NPAAO film thickness, enhanced absorption over the solar spectral range. Therefore, the solar absorptivity increased with the thickness of the NPAAO film, and more of the penetrating light was trapped by the thicker NPAAO film due to its greater depth and higher pore density. Moreover, the transient temperature of the NPAAO films was measured under 500 W halogen light illumination to investigate the photothermal efficiency of the films. The results indicated that the steady-state temperature increased with the absorptivity of the NPAAO films. The mean reflectance of the aluminum alloy specimens in the spectral range of 250-850 nm was greater than 72% before the anodizing oxidation process and less than 7.7% after the process. Therefore, the applied anodic voltage, which changes the pore density and the thickness of the anodized film, is an important factor determining the solar absorption performance of NPAAO films.
