“…The down-conversion technique, also regarded as quantum cutting, is usually attained by doping active ions of divalent or trivalent lanthanide elements into the transparent host material [369][370][371]. These lanthanide ions have abundant active states owing to the atomic structure that allows them to absorb light and emit photons at the broad spectrum from UV to IR [372,373]. This technique can effectively reduce the thermalization losses contributed by the high energy photons and also assist in increasing the photocurrent generation.…”

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.

“…These ions have abundant excited states, a virtue of their atomic structure, allowing them to absorb and emit photons across the light spectrum from UV to IR [97,98].

Due to the inherent broadband nature of the solar radiation, combined with the narrow spectral sensitivity range of direct solar to electricity devices, there is a massive opportunity to manipulate the solar spectrum to increase the functionality and efficiency of solar energy conversion devices. Spectral splitting or manipulation facilitates the efficient combination of both high-temperature solar thermal systems, which can absorb over the entire solar spectrum to create heat, and photovoltaic cells, which only convert a range of wavelengths to electricity. It has only recently been possible, with the development of nanofabrication techniques, to integrate micro-and nano-photonic structures as spectrum splitters/manipulators into solar energy conversion devices. In this paper, we summarize the recent developments in beam splitting techniques, and highlight some relevant applications including combined PV-thermal collectors and efficient algae production, and suggest paths for future development in this field.

To improve the utilization efficiency of chlorophyll to sunlight, Tm3+/Cr3+ codoped dual‐phase glass‐ceramics are successfully fabricated as a dual‐light conversion material by the conventional melt‐quenching technique with subsequent heat treatment. Exploiting the radius difference in atomic size, Tm3+ and Cr3+ ions have been rationally designed entering into the NaYF4 and NaAlSiO4 crystal phase, respectively, to avoid detrimental energy quenching. The resulted dual‐phase glass‐ceramics exhibit a great emission enhancement compared to the precursor glass. No obvious lifetime degradation in the codoped glass‐ceramic further proves the successful incorporation of Tm3+ and Cr3+ in distinguished crystalline phases. Utilizing the dual‐phase glass‐ceramics, the useless sunlight can be converted into the desired red/blue region and reabsorbed by the chlorophyll. The Tm3+ ions convert ultraviolet light into the blue region, and the Cr3+ ions transfer green light to the red emission. With the utilization of Tm3+/Cr3+ codoped dual‐phase glass‐ceramics in the greenhouse, the photosynthesis process can be promoted, and furthermore, the production of crops can be improved, indicating the potential applications in the field of green agriculture.
