“…However, the emergence of bimetallic nanoparticles (BMNPs), composed of two distinct elements, presents a unique opportunity to achieve optimal photonic device properties compared to their mono-metallic NP counterparts. 23,[29][30][31][32][33] Likewise, the optoelectronic properties of BMNPs in TFOSCs outshine that of their mono-metallic counterparts, due to their impressive light-scattering capabilities and far-reaching LSPR effects. In this novel investigation, the crown jewel of metal NPs in TFOSCs is silver (Ag), which has impressive LSPR effect and light-scattering properties in the dielectric medium, to be reckoned with for enhanced photons harvesting.…”

“…This novel approach offers multiple benefits, such as enhanced light absorption and improved device performance in TFOSCs 21,22 . One cannot overlook the fact that the localized surface plasmonic resonance (LSPR) and surface plasmonic resonance (SPR) owe their existence to the significant interplay between the electromagnetic (EM) field of the incident photon and the surface electron plasma of the metal nanocomposites 23 . The potential impact of LSPR and SPR may vary based on the size and geometry of metal nanoparticles (NPs).…”

“…The utilization of prominent synthesized metal NPs, such as silver (Ag), copper (Cu), nickel (Ni), zinc (Zn), and gold (Au), has been predominantly limited to mono‐metal NPs, which are competent at capturing incident photons through the LSPR effect. However, the emergence of bimetallic nanoparticles (BMNPs), composed of two distinct elements, presents a unique opportunity to achieve optimal photonic device properties compared to their mono‐metallic NP counterparts 23,29–33 …”

It is to be noted that the resonance condition can be fascinatingly observed when the frequency of light aligns with the frequency of oscillating electrons, commonly referred to as LSPR, in the context of nano-sized structures.…”

Tuning charge transport properties using silver‐cobalt bimetallic nanoparticles is investigated to enhance the photo‐current collection in polymer solar cells. The silver‐cobalt nanoparticles were not only augmenting the charge transport processes but also expected to trap light by way of reflection. The polymers blend consisting of poly‐(3‐hexylthiophene) (P3HT):[6,6]‐phenyl C61 butyric acid methyl ester (PC61BM) is used in the fabrication of polymer solar cells. The experimental results indicated that the solar cells' performance depended on the concentration of Ag/Co in the hole transport layer (HTL). Nevertheless, the high‐power conversion efficiency value of up to 4.21% was observed, at the concentration of 0.1% by weight, which is much higher than pristine solar cells due to improved measured photocurrents from the devices. This is a significant improvement in PCE by 66.4% compared to the undoped transport medium. Ag/Co nanocomposite is found to be more stable under ambient laboratory conditions.

Due to the negative impact and possible run out of fossil fuels, the use of an alternative source of energy, which is plentiful, is crucial. The use of sunlight to produce energy by means of photovoltaic cell devices is the perfect approach to deal with the disadvantages of fossil fuels. Now, the photovoltaics that are already in market because of their power conversion efficiency (PCE) and stability are based on inorganic materials. These inorganic materials are however faced with drawbacks such as toxicity and high fabrication cost. Changing inorganic materials to organic overcome those drawbacks making organic photovoltaic cells (OPVs) of importance. The problem with the OPVs is the low PCE and low stability. For decades now, researchers have been trying to improve the performance of OPVs by modifying active layer materials with the PCE of over 19% reached. This performance was achieved by performing intensive investigations to understand how the materials used in OPVs affect their performance. Our work highlights recent advancements on how the structures and chemical makeups of the active layer materials affects photovoltaic processes and performance in terms of power conversion efficiency and stability. It further sheds lights on the performance optimization of OPV and the relationship between these optimization conditions and OPV performance. The use of different substituents on the same donor or acceptor material has different optimal conditions. Furthermore, we showed how addition of different third components in the active layer have different optimal concentration point. This review also highlights and suggests a possible way to improve stability of OPVs through modification of the active layer. To date, some studies showed that incorporation of third component in the active layer led to over 97% stability after more than 1000 h.This article is protected by copyright. All rights reserved.
