“…49 or Cu 2 ZnSnS 4 solar cells, all of which exhibit the efficient AR performance, thus largely enhance the short-circuit current density. [51][52][53][54] ZnO nanostructured arrays are also used to construct hierarchical structures combined with other materials because of the facile fabrication of ZnO NSAs on arbitrary substrates. Notably, Qi et al adopted silicon micro-pyramids, which were prepared by photolithography followed by anisotropic etching process in KOH solution, as the starting substrate for the hydrothermal growth of ZnO nanorods (Fig.…”

Reducing the reflection and improving the transmission or absorption of light from wide angles of incidence in a broad wavelength range are crucial for enhancing the performance of the optical, optoelectronic, and electro-optical devices. Inspired by the structures of the insect compound eyes, nanostructure arrays (NSAs) have been developed as effective antireflective surfaces, which exhibit promising broadband and quasi-omnidirectional antireflective properties together with multifunctions. This review summarizes the recent advances in the fabrication and performance of antireflective surfaces based on NSAs of a wide variety of materials including silicon and non-silicon materials. The applications of the NSA-based antireflective surfaces in solar cells, light emitting diodes, detection, and imaging are highlighted. The remaining challenges along with future trends in NSA-based antireflective surfaces are also discussed.

“…In the first step, bilayered metallic CuInGa precursors of $0.6 lm were prepared using two ternary CuInGa alloys targets in a sputtering system. 12 A conventional CuInGa layer of Ga/(In þ Ga) ratio $ 0.28 (520 nm in thickness) was deposited on the Mocoated SLG substrates, and subsequently covered by an ultra-thin precursor layer of Ga/(In þ Ga) ratio $ 0.60 (80 nm in thickness). The atomic compositions of bi-layered CuInGa precursors were confirmed to be the ratios of Cu/ (In þ Ga) $ 0.87 and Ga/(In þ Ga) $ 0.31, respectively.…”

A low-toxic selenization with post gallium diffusion (PGD) treatment has been demonstrated to increase the bandgap in the surface Cu(In,Ga)Se 2 (CIGSe) absorbers and to form double-graded bandgap profiles to improve the cell efficiency. The CIGSe absorber with PGD for 5 min increased open-circuit voltage from 0.49 to 0.66 V and efficiency from 9.2% to 13.2%, contributed by the enhancement of carrier recombination in the space-charge region. The reduction in short-circuit current from 30.8 to 29.9 mA/cm 2 , attributed to the absorption loss in long-wavelength regions, can be potentially improved by further optimization of the minimum bandgap value in gradient valley.

Invisibility dips, i.e., minima in scattering spectrum associated with asymmetric Fano-like line-shapes, have been predicted with transformation optics in studying strong coupling between two plasmonic nanoparticles. This feature of strongly coupled plasmonic nanoparticles holds promise for sensor cloaking. It requires an extremely narrow gap between the two nanoparticles, preventing its experimental observation at optical frequencies. Here, the concept of spoof surface plasmons is used to facilitate the strong coupling between two spoof-localized-surface-plasmon (SLSP) resonators. Instead of observing in far field, the near-field energy transport is probed through the two SLSP resonators. By virtue of enhanced coupling between the two resonators stacked vertically, a spectral transmission dip with asymmetric Fano-like line-shape, similar to the far-field "invisibility dips" predicted by transformation optics, is observed. The underlying mode interference mechanism is further demonstrated by directly imaging the field maps of interfered waves that are tightly localized around the resonators. These near-field "invisibility dips" may find use in near-field sensing, on-chip switching, filters, and logical operation elements.
