“…Comparing to previously reported Ag nanospheres on Si nanopillar arrays (with a height of 300 nm) which sit on Si substrates [25], although this structure (with a height of 210 nm) is shorter, the average reflectance (1.8%) of this structure is smaller than that (∼2.7%) of Ag nanospheres on Si nanopillar arrays, and the average transmission (93.1%) of this structure is much higher than that (∼82.4%) of Ag nanospheres on Si nanopillar arrays. Besides, the average reflectance (1.8%) of this structure in the 400-1100 nm range is smaller than that (∼7%) of the Mie resonator arrays composed of compacted TiO 2 nanoparticles [28].…”

A structure of periodic Si nanopillar dimer array & Si3N4 layer which sits on Si substrates is presented to obtain a broadband high transmission and low reflection. We show numerically that the average reflection of this structure can reach 1.8%, and the average transmission can reach 93.1% in the 400–1100 nm range, due to the combined effects of the forward scattering effects of Si nanopillar dimers and Si3N4 layer’s anti-reflection effects. Si nanopillars’ diameter and height, Si3N4 layer’s height, the gap of dimers, and the period of the array have significant impacts on the transmittance and reflection. This work supplies a practicable way for decreasing broadband surface reflection and increasing the absorption of light for Si solar cell applications.

“…Some research has shown that metal nanoparticles can decrease the thickness of anti-reflective coatings. And metal nanoparticles can decrease the surface reflection due to the support of localized surface plasmon resonances [14][15][16][17][18][19][20][21][22][23][24][25]. However, metal materials have significant absorption losses.…”

“…The transmittance values of ARCs with 0.10 wt % Ag annealed at 400 • C were 95.7% and 97.2% for single-side, and both sides coated glass samples in the visible wavelength range. Recently, Huang created a broadband low reflection ARC with Ag nanospheres on Si nanopillar arrays [234]. The results showed that the average reflection reached up to 2.66% in 400-1100 nm wavelength range owing to the AR properties of Si nanopillars and the forward scattering effect of Ag nanospheres.…”

The solar photovoltaic (PV) cell is a prominent energy harvesting device that reduces the strain in the conventional energy generation approach and endorses the prospectiveness of renewable energy. Thus, the exploration in this ever-green field is worth the effort. From the power conversion efficiency standpoint of view, PVs are consistently improving, and when analyzing the potential areas that can be advanced, more and more exciting challenges are encountered. One such crucial challenge is to increase the photon availability for PV conversion. This challenge is solved using two ways. First, by suppressing the reflection at the interface of the solar cell, and the other way is to enhance the optical pathlength inside the cell for adequate absorption of the photons. Our review addresses this challenge by emphasizing the various strategies that aid in trapping the light in the solar cells. These strategies include the usage of antireflection coatings (ARCs) and light-trapping structures. The primary focus of this study is to review the ARCs from a PV application perspective based on various materials, and it highlights the development of ARCs from more than the past three decades covering the structure, fabrication techniques, optical performance, features, and research potential of ARCs reported. More importantly, various ARCs researched with different classes of PV cells, and their impact on its efficiency is given a special attention. To enhance the optical pathlength, and thus the absorption in solar PV devices, an insight about the advanced light-trapping techniques that deals with the concept of plasmonics, spectral modification, and other prevailing innovative light-trapping structures approaching the Yablonovitch limit is discussed. An extensive collection of information is presented as tables under each core review section. Further, we take a step forward to brief the effects of ageing on ARCs and their influence on the device performance. Finally, we summarize the review of ARCs on the basis of structures, materials, optical performance, multifunctionality, stability, and cost-effectiveness along with a master table comparing the selected high-performance ARCs with perfect AR coatings. Also, from the discussed significant challenges faced by ARCs and future outlook; this work directs the researchers to identify the area of expertise where further research analysis is needed in near future.
