“…The PCE enhancement was attributed to the high scattering power of Ag NPs and the broad spectral response of Au NPs in the long-wavelength range [ 21 ]. Core-shell, metal nanostructures, bimetallic, and mixed metal nanoparticles have been incorporated in the buffer, active layer, or both to enhance absorption in a broad wavelength range [ 14 , 21 ]. Kacus et al improved PCE from 2.11 to 2.55% by embedding Au NPs into the active layer; a 2.23% increase was reported using Ag NPs in the same active layer [ 10 ].…”

“…The study reported an increase in the short-circuit current density (

) and fill factor (FF) (

) to 15.5

and 0.49%, respectively, when compared to reference PEDOT: PSS with 15.4

and FF of 0.45% [ 8 ]. However, the limitation of incorporating NPs into the photoactive layer is that the NPs can become charge recombination centers that introduce exciton quenching and non-radiative energy interaction between the metal NPs and active layers, resulting in an overall reduction in efficiency [ 14 , 22 ]. All of these results were conducted with fullerene-based OSC.…”

Organic-based photovoltaics are excellent candidates for renewable energy alternatives to fossil fuels due to their low weight, low manufacturing cost, and, in recent years, high efficiency, which is now above 18%. However, one cannot ignore the environmental price of the fabrication procedure due to the usage of toxic solvents and high-energy input equipment. In this work, we report on the enhancement of the power conversion efficiency non-fullerene organic solar cells by incorporating green synthesised Au–Ag nanoparticles, using onion bulb extract, into the hole transport layer poly (3,4-ethylene dioxythiophene)-poly (styrene sulfonate) (PEDOT: PSS) of Poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b′]dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3 fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl)]: 3,9-bis(2-methylene-(3-(1,1-dicyanomethylene)-indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2′,3′-d′]-s-indaceno[1,2-b:5,6-b′]dithiophene (PTB7-Th: ITIC) bulk-heterojunction organic solar cells. Red onion has been reported to contain quercetin, which serves as a capping agent that covers bare metal nanoparticles, thus reducing exciton quenching. We found that the optimized volume ratio of NPs to PEDOT: PSS is 0.06:1. At this ratio, a 24.7% enhancement in power conversion efficiency of the cell is observed, corresponding to a 9.11% power conversion efficiency (PCE). This enhancement is due to an increase in the generated photocurrent and a decrease in the serial resistance and recombination, as extracted from the fitting of the experimental data to a non-ideal single diode solar cell model. It is expected that the same procedure can be applied to other non-fullerene acceptor-based organic solar cells, leading to an even higher efficiency with minimal effect on the environment.

“…Moreover, the synthesis of excellent low band gap polymers, which improves the short-circuit current density ( J sc ), and the choice of new device architecture also play essential roles to boost the power conversion efficiency of polymer solar cells. Especially metallic nanoparticles that exhibit localized surface plasmon resonance (LSPR), light scattering, and surface plasmon polaritons (SPPs) have been widely utilized to achieve high photon harvesting and improved carrier mobility within the absorber layer. − Reports suggest that plasmonic nanostructures that have the LSPR effect in the active layer or buffer layer have proved to be one of the most practical ways to improve optical absorption by increasing the optical path length of the incident photons and increase light trapping. , It also assists with the collection of photogenerated charge carriers without increasing the physical thickness of the active layer. − The phenomena of plasmon resonance by metal nanoparticles are illustrated by Figure , where a number of interaction mechanisms are provided. The interaction of the incident photons with the surface electron plasma of the metal nanoparticles in the medium could be described by the following possible phenomena.…”

Reducing Energy Loss in Polymer Solar Cell through Optimization of Novel Metal Nanocomposite

Ag/CuPO4 nanocomposite was successfully synthesized using wet chemistry for potential application as a mechanism to suppress charge recombination and harvest more photons in thin-film organic solar cells (TFOSCs). The morphological and optical properties of the nanocomposite were studied using high-resolution electron microscopy and UV–vis spectroscopy. The Ag/CuPO4 nanocomposite exhibited a semispherical geometry which is suitable for the occurrence of localized surface plasmon resonance (LSPR) and light scattering in a dielectric medium. Conventional device architecture is employed that uses a solar absorber composed of a poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) blend with and without the nanocomposite. As a result, significant changes in the device performances were observed by the incorporation of the metal nanocomposite, where the experimental evidence suggested that the doped active layer outperformed the undoped ones. Consequently, the best power conversion efficiency (PCE) grew by nearly 95% compared to the reference cell. Furthermore, the measured photocurrents are found to be dependent on the concentration of the nanocomposite in the absorber layer. In this article, the effects of metal nanocomposite are discussed in terms of the phenomena of local surface plasmon resonance and far-field scattering in the photoactive medium of TFOSCs.

Solar energy technologies provide solutions for the effective exploitation of internet of things (IoT)‐based applications such as smart devices. Organic photovoltaics (OPVs) fabricated from π‐conjugated carbon‐based semiconductors have shown great potential for indoor applications based on exceptional properties that include small current leakage under dim lighting, large absorption coefficient, and low‐cost solution processes. However, organic cells need additional enhancements, such as improving their dim light absorption and exploiting suitable bandgap materials, to make the best use of indoor lighting photons. This article highlights the crucial role of the theoretical basis of photovoltaics and reviews the effect of active layer thickness. Furthermore, the crucial advancements in material design for indoor OPVs are highlighted herein. Lastly, the contribution of plasmonic effect of metallic nanoparticles (MNPs) to improve the performance of OPVs is elaborated, which could contribute to raising the efficiency of energy conversion and reaching production scale criteria.
