“…The matrix can typically be inorganic, [496][497][498][499] sol-gel based matrix [215,[500][501][502][503][504][505][506][507][508][509][510] or polymers. [511][512][513][514] Regarding the in situ growth, the main drawbacks are the limitations in terms of control of the shape of the particles, which are often spherical or wire-type structures and the homogeneity in size and dispersion. The control of the growth using laser and in particular two-photon induced fabrication is limited to micrometer size in resolution.…”

“…[521] Multilayers systems can be an alternative to control interactions between metal NPs and luminescent polymers. [513,[522][523][524] M. Mitsuishi et al used also hybrid polymer approach combining polymer nanosheets nanoassemblies through LangmuirBlodgett technology and introduced metal nanoparticles layers. [522,523] The polymer layer part included chromophores (for luminescence or NLO), and the distance to the nanoparticles deposited on the films or between two films was controlled by the length and the thickness of the polymers.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

“…Therefore, the exploitation of LSPR of Ag and Au nanostructures is one of the key approaches to increase the optical absorption, by light trapping, in thin film Si solar cells, organic solar cells, and new-generation solar cells [ 1 , 2 , 3 , 4 , 5 , 13 , 14 ]. So, several schemes for functional devices incorporating plasmonic Ag and Au nanoparticles were recently proposed [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Generally, this can be achieved by the scattering of light, by the metal nanoparticles, at the cell’s interfaces, either by transmission at the top interfaces or by reflection at the rear ones [ 34 ].…”

“…For specific resulting performances, so, the system needs to be geometrically optimized to maximize scattering and minimize light absorption within the metal nanoparticles across the wavelength range of interest. In solar cell applications, the Ag or Au nanoparticles are usually supported on or embedded in a thin transparent conductive oxide (TCO) layer [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. TCOs are widely used as transparent electrodes for a variety of solar cell devices [ 35 ].…”

Ag and Au nanostructures became increasingly interesting due to their localized surface plasmon resonance properties. These properties can be successfully exploited in order to enhance the light trapping in solar cell devices by appropriate light scattering phenomena. In solar cell applications, the Ag or Au nanoparticles are, usually, supported on or embedded in a thin transparent conductive oxide layer, mainly AZO and ITO for inorganic solar cells and PEDOT:PSS for organic solar cells. However, the light scattering properties strongly depend on the shape and size of the metal nanostructures and on the optical properties of the surrounding environment. Therefore, the systems need to be well designed to maximize scattering and minimize the light absorption within the metal nanoparticles. In this regard, this work reports, in particular, results concerning calculations, by using the Mie theory, of the angle-dependent light scattering intensity (I(θ)) for spherical Ag and Au nanoparticles coated by a shell of AZO or ITO or PEDOT:PSS. I(θ) and scattering efficiency Qscatt for the spherical core–shell nanoparticles are calculated by changing the radius R of the spherical core (Ag or Au) and the thickness d of the shell (AZO, ITO, or PEDOT:PSS). For each combination of core–shell system, the evolution of I(θ) and Qscatt with the core and shell sizes is drawn and comparisons between the various types of systems is drawn at parity of core and shell sizes. For simplicity, the analysis is limited to spherical core–shell nanoparticles so as to use the Mie theory and to perform analytically exact calculations. However, the results of the present work, even if simplified, can help in establishing the general effect of the core and shell sizes on the light scattering properties of the core–shell nanoparticles, essential to prepare the nanoparticles with desired structure appropriate to the application.

“…[29][30][31] By adding metal NPs in OPVs, two effects can be excited; on the one hand the localized surface plasmon resonance (LSPR) effect 20,21 and on the other the light trapping effect by scattering the incident light at wide angles. [32][33][34][35] In the case of HTL, different metallic NPs have been implanted into the PEDOT:PSS layer showing that the performance enhancement was due to hole collection improvements and reduced exciton quenching. 27,[36][37][38][39][40] The incorporation of surfactant free Al NPs, produced by laser ablation method 41 is another promising approach, owing to their relative large diameter reaching tens of nms, 42 combined with the high plasma frequency of Al; the frequency, in which the electrons oscillate back at forth.…”
