“…In order to improve the efficiency of solar cells, b-Si needs excellent surface passivation [ 11 ]. Although a wide variety of films can be selected, such as SiN x [ 12 ] and SiO 2 [ 13 ], the Al 2 O 3 thin film deposited by atomic layer deposition (ALD) is the best choice for passivating b-Si [ 14 ]. On the one hand, ALD, which has a conformal growth on surface with high aspect ratio features [ 15 ] and pinhole-free nature [ 16 ], is the natural choice for the coating of nanostructured surfaces.…”

Black silicon shows excellent anti-reflection and thus is extremely useful for photovoltaic applications. However, its high surface recombination velocity limits the efficiency of solar cells. In this paper, the effective minority carrier lifetime of black silicon is improved by optimizing metal-catalyzed chemical etching (MCCE) method, using an Al2O3 thin film deposited by atomic layer deposition (ALD) as a passivation layer. Using the spray method to eliminate the impact on the rear side, single-side black silicon was obtained on n-type solar grade silicon wafers. Post-etch treatment with NH4OH/H2O2/H2O mixed solution not only smoothes the surface but also increases the effective minority lifetime from 161 μs of as-prepared wafer to 333 μs after cleaning. Moreover, adding illumination during the etching process results in an improvement in both the numerical value and the uniformity of the effective minority carrier lifetime.

This article introduces resonant cavity antennas (RCAs) and leads the reader to develop an operational understanding of the design processes and considerations related to various types of RCAs. RCAs are a class of medium‐to‐high gain antennas, often having a single excitation location (as opposed to antenna arrays) and a simple configuration. These are a convenient alternative to antenna arrays and reflector antennas in space‐constrained applications where robustness, performance, and aesthetic appeal are equally important. The article discusses recent research results and trends particularly focusing on advances that have the potential to yield practical advantages, such as compactness, low profile, and high efficiency. The article reviews progress on gain bandwidth enhancement, achieving high aperture efficiency, multiband operation, and methods for aperture phase correction in RCAs.
