“…The incident light will reflect between the sloped surfaces, strengthening the interaction between the incident light and the semiconductor surface. The second layer is protected by a single or multi-layer antireflective coating [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. These coatings are typically very thin, with an optical thickness of about one-quarter to one-half the incident wavelength.…”

“…These coatings are typically very thin, with an optical thickness of about one-quarter to one-half the incident wavelength. The antireflector single-layer coating is only effective against reflection for a single wavelength, resulting in high-quality solar cells [38][39][40][41][42][43][44][45][46][47][48][49][50]. Precise PV modules optical assessment is not easy.…”

In this research, a detailed abacus adventure and statistic obsession are made to survey the relation of fractions of materials of the anti-reflective coating to effectiveness of a solar cell. Emphasis on the study of whether single or double-layer layers of coatings save energy reflection and improve absorption is done leading to energy conservation. The anti-reflective coating is a familiar term in the solar technology, as it is less realistic without the coating that minimizes the light reflection losses. By way of single or double coating, light transmission increased is by limiting reflection therefore making the surfaces of solar cells to receive more light improving efficiency. These finer details of the coating's power over the solar cells' light absorption depth and output effectiveness are thoughtfully and minutely deliberated. A great deal of numerical methods are used to model light and sunlight impinging on the coated solar cell environments. Light waves' behaviour, when meet an antireflection layer, is a very important aspect in explaining, to some extent, about the thickness of the layer and its materials composition. That is a great role, namely, statistical techniques in this study whose purpose is used to main performance gain in the solar cells. Through simulation and experimental data, correlations are established between solar cell performance and the coating’s parameters. The patterns found will be taken into consideration to further improve the coating. This research, not just performed steps by step analysis of reflection, absorption and power conversion features in solar cells coated; rather, guidelines to excellent anti-reflective coating were offered too. The clarification of complex connections between the performance of coating construction and solar cells performance is enabled in this research and its results significantly contribute towards the development of renewable energy engineering, hence giving the research a certain weight in the field of solar energy.

“…Considerable effort has gone into developing methods by which to increase the conversion efficiency of C-Si solar cells, including the formation of pyramidal surface structures and the application of anti-reflective coatings [8][9][10][11][12]. Nonetheless, the conversion efficiency of C-Si solar cells at shorter wavelengths (UV-blue band) remains low due to three key issues: (1) lower responsivity of C-Si in the UV-blue wavelength range; (2) loss of higher energy incident photons within a short distance of the surface due to photo-carrier recombination caused by surface defects; (3) energy loss via thermalization when high energy photons generate carriers with excessive energy [13][14][15].…”

Luminescent down-shifting (LDS) spectral conversion is a feasible approach to enhancing the short-wavelength response of single junction solar cells. This paper presents the optical and electrical characteristics of LDS spectral conversion layers containing a single species or two species of Eu-doped phosphors applied to the front surface of silicon solar cells via spin-on coating. The chemical composition, surface morphology, and fluorescence emission of the LDS layers were respectively characterized using energy-dispersive X-ray analysis, optical imaging, and photoluminescence measurements. We also examined the LDS effects of various phosphors on silicon solar cells in terms of optical reflectance and external quantum efficiency. Finally, we examined the LDS effects of the phosphors on photovoltaic performance by measuring photovoltaic current density–voltage characteristics using an air-mass 1.5 global solar simulator. Compared to the control cell, the application of a single phosphor enhanced efficiency by 17.39% (from 11.14% to 13.07%), whereas the application of two different phosphors enhanced efficiency by 31.63% (from 11.14% to 14.66%).

“…For instance, in the air atmosphere, a polished silicon surface reflects >30% of the incident solar radiations (Thomas et al, 1989). Therefore, to reduce optical loss due to high reflectivity and improve the energy harvesting capability of solar cells, different solutions have been proposed such as the utilization of the antireflective coatings (ARCs), surface texturization, or a combination of both to increase the optical path length of the light within solar cells (Singh and Verma, 2019;Abu-Shamleh et al, 2021;Sagar and Rao, 2021).…”

“…Other oxides such as Ta 2 O 5 (Thomas et al, 1989;Sagar and Rao, 2021) could offer better antireflective properties but are not good enough for photocatalytic degradation of environmental contaminants. Therefore, these oxides are often used in combination with TiO 2 to form self-cleaning ARCs.…”

Antireflective Self-Cleaning TiO2 Coatings for Solar Energy Harvesting Applications

et al. 2021

View full text Add to dashboard Cite

Titanium(IV) oxide (TiO2, titania) is well-known for its excellent photocatalytic properties, wide bandgap, chemical resistance, and photostability. Nanostructured TiO2 is extensively utilized in various electronic and energy-related applications such as resistive switching memory devices, flat panel displays, photodiodes, solar water-splitting, photocatalysis, and solar cells. This article presents recent advances in the design and nanostructuring of TiO2-containing antireflective self-cleaning coatings for solar cells. In particular, the energy harvesting efficiency of a solar cell is greatly diminished by the surface reflections and deposition of environmental contaminants over time. Nanostructured TiO2 coatings not only minimize reflection through the graded transition of the refractive index but simultaneously improve the device’s ability to self-clean and photocatalytically degrade the pollutants. Thus, novel approaches to achieve higher solar cell efficiency and stability with pristine TiO2 and TiO2-containing nanocomposite coatings are highlighted herein. The results are compared and discussed to emphasize the key research and development shortfalls and a commercialization perspective is considered to guide future research.
