“…In general, plasma effect is triggered by incorporating metal nanostructures into CTL such as hole transport layer of poly(3,4-e thylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) [30,33,[102][103][104][105], WO X [5,9,106] and MoO X [32], electron transport layer of TiO X [36][37][38] and ZnO [35,52,107]. The performance of OSCs has been improved by various methods, such as plasmonic resonance, light scattering, promotion of exciton separation and transfer, electron accumulation, and improving interfacial morphology.…”

“…Diukman et al showed an improvement in the external quantum efficiency of OPV solar cells after embedding Au nanoparticles arrays in the active layer [27]. Kekeli et al reported an enhancement in intrinsic optical absorption in the active layer, with and without the square lattice of core-shell (Ag@Sio2) by 24.7% [22]. The Au nanoparticles, which are on the order of 5-50 nm, act as antennas, accumulating incident light energy in localized surface plasmon modes with up to a 100-fold increase in electric field.…”

In this paper, the light absorption the active layer of polymer polymer solar cells (OPV) by using plasmonic nanocrystals with hexagonal lattice is investigated. To study the relation between the performance of the OPV solar cell and its active layer, a three-dimensional model for its morphology is utilized. Therefore, the threedimensional (3D) finite-difference time-domain method and Lumirical software were used to measure the field distribution and light absorption in the active layer in terms of wavelength. OPV solar cells with bilayer and bulk heterojunction structured cells were designed using hexagonal lattice crystals with plasmonic nanoparticles, as well as, core-shell geometry to govern a design to optimize light trapping in the active layer. The parameters of shape, material, periodicity, size, the thickness of the active layer as a function of wavelength in OPV solar cells have been investigated. A very thin active layer and an ultra-thin shell were used to achieve the highest increase in optical absorption. The strong alternating electromagnetic field around the core-shell plasmonic nanoparticles resulting from the localized surface plasmon resonance (LSPR) suggested by the Ag plasmonic nanocrystals increased the intrinsic optical absorption in the active layer poly(3-hexylthiophene):phenyl-C61butyric acid methyl ester (P3HT:PCBM). Based on the photovoltaic results the short circuit current ranged from 19.7 to 26.7 / 2.

“…[18][19][20] To overcome such problems, these MNPs can be insulated with a dielectric shell as core (metal)-shell (dielectric) NPs; this successful approach was detailed in our previous studies. [21][22][23][24][25] The chemical synthesis of the core-shell NPs with the expected parameters (dispersion, size, shell thickness etc.) has to be well controlled.…”

Embedding metallic nanoparticles (MNPs) in organic solar cells (OSCs) is proposed as one of the promising strategies to enhance their photovoltaic performance owing to localized surface plasmon resonance, light scattering effects or a synergy of both effects derived from the MNPs. However, it has been demonstrated that MNPs wrapped by a thin dielectric silica shell can lead to better photovoltaic yield than bare MNPs due to the presence of the dielectric shell which avoids direct contact between the active layer and the MNPs, reducing the charge recombination and the exciton quenching loss at the metal surface. In this study, we report an alternative solution using an ultrathin dielectric layer coating silver nanoparticles (Ag NPs) for improving the performance of plasmonic inverted OSCs instead of the use of metal–dielectric core–shell NPs. A silica (SiO2) layer 5 nm thick coating evaporated Ag NPs with an average size of 60 nm is deposited on top of the zinc oxide (ZnO) layer used as the electron transport layer, leading to a significant improvement in the short‐circuit current density (Jsc) and the power conversion efficiency (PCE) of the inverted OSCs. The electron‐beam evaporation method is employed for controlled deposition of Ag NPs and SiO2 on the ZnO layer. The plasmonic devices resulted in an 18% and 14.1% enhancement of the Jsc and PCE, respectively, compared to reference devices. This increase of the photoelectric parameters in plasmonic devices is attributed not only to the plasmonic effects originating from the Ag NPs but also to the ultrathin silica layer which can contribute to facilitating charge extraction. © 2019 Society of Chemical Industry
