Hyperbolic metamaterials have been widely used for nonlinear optical applications. Their unique functionality for nonlinear optics enhancement due to the hyperbolic dispersion is induced by a strong shape anisotropy. In this work, we numerically investigated the second-harmonic generation (SHG) in two-dimensional periodic arrays of aluminium gallium arsenide (AlGaAs) nanowires embedded in ordered porous aluminum oxide (Al2O3) or the nanowire hyperbolic metamaterial (NHMM). Under local effective medium approximation, the homogenization of the NHMM was achieved due to deep sub-wavelength size of each nanowire radius. Then this medium was classified as an effective uniaxial medium with anisotropic electric permittivity. The NHMM provided the spectral position of second-harmonic (SH) wavelength, which is determined at the epsilon-near-zero (ENZ) by the optimal design of NHMM structural parameters such as AlGaAs radius or fill fraction. Consequently, a gigantic increment of SHG conversion efficiency was achieved because of dramatic phase-matching at ENZ point. This mechanism is attributed to electric field enhancement of SHG inside the metamaterial. According to numerical results, the NHMM can be applied as nonlinear frequency converters in integrated nanophotonic systems. © 2023 SPIE.

The current situation necessitates advancements in renewable energy to serve as a viable alternative to traditional energy sources. The photovoltaic cells can entirely change the need for fossil fuels since they can transform light energy into electrical energy. The reflection loss in photovoltaic cells is a contributing factor to reduced power conversion efficiency that could be mitigated by using antireflective coatings on the surface of the solar cells. This study examines the deposition of zinc stannate (ZnSnO3) as an efficient antireflective material to improve light capturing capability and it is synthesized by sol-gel method. The electro spraying method was employed to deposit the ZnSnO3 layers on photovoltaic cells. The ZnSnO3 AR material was uniformly distributed on the solar substrate at 2 ml/h for 1 h (Z1), 2 h (Z2), 3 h (Z3) and 4 h (Z4) respectively. The impact of ZnSnO3 ARC on the structural, electrical, absorbance, reflectance characteristics and temperature variation in monocrystalline silicon (m-Si) solar cells was examined. The optical properties were determined by UV–visible spectroscopy technique. At a wavelength (300–800 nm), the ZnSnO3 coated for 3 h (Z3 specimen) exhibited highest absorbance of 92.65 % and the lowest electrical resistivity of 3.69 × 10−3 Ω-cm. When compared with bare and various ZnSnO3 coated cells, Z3 specimen showed a significant impact on solar cell efficiency. In direct solar radiation and stimulated light, the Z3 specimen achieved the maximum power conversion efficiency (PCE) of 21.16 % and 25.11 %. The findings indicated that ZnSnO3 could be a suitable AR coating material for reducing incoming photon reflection. © 2025 Elsevier Ltd and Techna Group S.r.l.

With the increasing adoption of solar energy as a sustainable power source, it is crucial to evaluate the performance of photovoltaic (PV) modules under diverse environmental conditions to ensure optimal energy production and system efficiency. Present work gives a comprehensive overview of performance assessment and validation studies conducted on different PV module technologies such as multi-crystalline silicon (mc-Si), cadmium telluride (CdTe), copper indium gallium selenide (CIGS), amorphous silicon (a-Si), heterojunction with intrinsic thin layer (HIT) and interdigitated back contact (IBC) operating under varied climatic conditions at different locations in India. To ensure accuracy and reliability, rigorous data collection and analysis methodologies were employed. The performance assessment has been computed through simulation using PVSOL software. Moreover, the performance ratio (PR) of all the PV module technologies was found to vary from 0.76 to 1.04. The present work validates the efficacy of the software as we have compared the computed results with real-time data obtained for all the PV modules, which were installed at NISE (National Institute of Solar Energy), Gurugram India. The performance ratio of all the PV module technologies has been evaluated through both the PVSOL and using real time data. The results show that the mean percentage change in PR values has been estimated approximately to be 2% in CdTe, CIGS, and a-Si modules technologies and 3% in mc-Si, HIT and IBC module technologies. © 2023
