“…In this way, we enable the use of Maxwell Garnett EMT or equivalent EMTs for the modeling of state-of-the-art plasmonic photocatalytic systems in which metal-semiconductor core-shell photocatalysts are supported in a matrix of arbitrary dielectric function [7,8]. Note that similar configurations are also widely used in solar energy harvesting applications [9][10][11]. This procedure is illustrated in Figure 1: the proposed approach is used to calculate the effective dielectric function of the core-shell inclusions cs .…”

The possibility of using light to drive chemical reactions has highlighted the role of photocatalysis as a key tool to address the environmental and energy issues faced by today’s society. Plasmonic photocatalysis, proposed to circumvent some of the problems of conventional semiconductor catalysis, uses hetero-nanostructures composed by plasmonic metals and semiconductors as catalysts. Metal-semiconductor core-shell nanoparticles present advantages (i.e., protecting the metal and enlarging the active sites) with respect to other hetero-nanostructures proposed for plasmonic photocatalysis applications. In order to maximize light absorption in the catalyst, it is critical to accurately model the reflectance/absorptance/transmittance of composites and colloids with metal-semiconductor core-shell nanoparticle inclusions. Here, we present a new method for calculating the effective dielectric function of metal-semiconductor core-shell nanoparticles and its comparison with existing theories showing clear advantages. Particularly, this new method has shown the best performance in the prediction of the spectral position of the localized plasmonic resonances, a key parameter in the design of efficient photocatalysts. This new approach can be considered as a useful tool for designing coated particles with desired plasmonic properties and engineering the effective permittivity of composites with core-shell type inclusions which are used in photocatalysis and solar energy harvesting applications.

“…The maximum PCE of 16.3% was reported in perovskite solar cell having plasmonic structure [11]. More recently, the role of NPs in perovskite solar cells has been investigated theoretically [13], [14]. They showed Au@SiO2 core-shell NPs provide optical absorption enhancement in perovskite solar cells, where the perovskite material itself has relatively poor absorption.…”

“…They showed Au@SiO2 core-shell NPs provide optical absorption enhancement in perovskite solar cells, where the perovskite material itself has relatively poor absorption. Also, they showed Au@SiO2 NPs with a SiO2 shell thickness of ∼1 nm provided greater absorption enhancement than the NPs with thicker shells [13]. In previous work, our group studied the plasmonic effects of Ag NPs (Ag NPs without shell) on the photovoltaic characteristics of mesoporous heterojunction HTL-free perovskite solar cells [15].…”

To investigate the plasmonic effect in perovskite solar cells, the effect of depositing Au@SiO2 nanoparticles on the top and the bottom of mesoporous TiO2 layers was studied. First, Au@SiO2 nanoparticles were synthesized. The particles were then deposited at the different interfaces of mesoporous TiO2 layers. Although the two structures show approximately similar optical absorption, only cells with Au@SiO2 nanoparticles deposited at the bottom of the mesoporous TiO2 layers demonstrated an improved photocurrent performance compared to the reference cells. This structure shows a short-circuit current density (JSC) of 20.7 mA/cm 2 and open circuit voltage of 1081 mV. This enhancement may be attributed either to the interface surface engineering or plasmonic resonance of Au@SiO2 nanoparticles depends to the NPs size and position.

Inorganic hole‐transporting materials (HTMs) profoundly improve the stability and robustness of the solar cell compared to that expected from organic HTMs. In this work, the efficiency of a perovskite solar cell is greatly enhanced using a hexagonal nanoprism array of inorganic metal oxide HTM. We found that the introduced structure increases the efficiency of the mesoscopic configuration by 42% higher than that of the planar perovskite solar cell with the same thickness of the active layers. The reason of this enhancement in power conversion efficiency is the better carrier transportation in the mesoscopic configuration. The periodic array of mesoscopic hole‐transporting layer is vastly tunable and reveals unique capabilities of designing a particular array, which can enhance the efficiency of the perovskite solar cell. We also incorporated plasmonic nanoparticles into the absorber layer and found that they significantly could improve the performance of the solar cell. The inclusion of spherical nanoparticles improves the light absorption of the bare mesoscopic solar cell. An increasing number of nanoparticles enhances the light trapping inside the active layer and as a result improves the probability of light absorption.
