“…It is observed from figure 8(a) that QE of the solar cell is higher for N D =10 14 cm −3 of Si substrate, whereas it decreases with Si doping concentration. This finding is consistent with the fact that J SC decreases with doping concentration, revealing that J SC is in consort with the QE [48]. For the case of CuI doping concentration, QE is almost independent of doping concentrations, N A >10 16 cm −3 , implying that J SC is almost independent of doping concentration of CuI thin film, as seen from figure 8(b).…”

We report the simulation outcomes of a highly efficient CuI/n-Si heterojunction solar cell (HJSC) by SCAPS-1D simulator using the parameters obtained from spin-coated CuI thin film characterizations. The influence of thickness and doping concentration of Si substrate as well as CuI hole transport layer (HTL) on the photovoltaic (PV) parameters and built-in potential has been explored. The optimum values of the solar cell parameters are presented to attain the best result. The highest power conversion efficiency (PCE) of 22.62% with J SC of 37.25 mA cm −2 , V OC of 0.716 V and FF of 84.69% has been achieved with a 200 μm thick Si substrate and 50 nm thick CuI thin film, respectively. Finally, the resistance dependent PV performance has been investigated for the solar cell. These findings indicate that highly efficient CuI/n-Si HJSC can be designed and this can be a potential candidate compared to the organic/Si HJSC counterpart.

“…By measuring the electrical properties of devices, the influence of Au NPs and QDs in the cell's performance is clarified. The increase in the broadband region between 600 nm and 850 nm is considered to be attributed to the plasmonic effect of Au NPs [15,17]. As mentioned, the significant absorbance in the UV range and the high photon emission intensity at 528 nm are the well-assist factors for significantly increasing light absorption in the Si layer, which contributes to the J SC enhancement [23].…”

“…This IPCE increase is assigned to the magnified light scattering effect [8][9][10]. However, the sole Au integrated solar cell reduces IPCE for photons possessing energy less than 2 eV, resulting from the back-scattering effect associated with Au NPs [15][16][17][18]. Meanwhile, the integration of cells with Au/QD layer further intensifies the J SC , from 14.86 mA/cm 2 to 19.56 mA/cm 2 , which is strongly suggested by the elevated IPCE value for broad spectrum.…”

“…Small sizes of MNPs (below 50 nm) are supposed to induce the intensive near-field localization; then, generate the light scattering in the board area of solar spectra [13,14]. However, plasmon assistance of MNPs on the semiconductor wafer leads to the external quantum efficiency (EQE) loss in the UV and near UV region that has already been testified [15][16][17][18]. Additionally, quantum dots (QDs) luminescent layers are applied as the other approach to enhance solar cell efficiency.…”

Recently, in the solar energy society, several key technologies have been reported to meet a grid parity, such as cost-efficient materials, simple processes, and designs. Among them, the assistive plasmonic of metal nanoparticles (MNPs) integrating with the downshifting on luminescent materials attracts much attention. Hereby, Si-based Schottky junction solar cells are fabricated and examined to enhance the performance. CdSe/ZnS quantum dots (QDs) with different gold nanoparticles (Au NPs) sizes were incorporated on a Si light absorbing layer. Due to the light scattering effect from plasmonic resonance, the sole Au NPs layer results in the overall enhancement of Si solar cell’s efficiency in the visible spectrum. However, the back-scattering and high reflectance of Au NPs lead to efficiency loss in the UV region. Therefore, the QDs layer acting as a luminescent downshifter is deployed for further efficiency enhancement. The QDs layer absorbs high-energy photons and re-emits lower energy photons in 528 nm of wavelength. Such a downshift layer can enhance the overall efficiency of Si solar cells due to poor intrinsic spectral response in the UV region. The optical properties of Au NPs and CdSe QDs, along with the electrical properties of solar cells in combination with Au/QD layers, are studied in depth. Moreover, the influence of Au NPs size on the solar cell performance has been investigated. Upon decreasing the diameters of Au NPs, the blueshift of absorbance has been observed, cooperating with QDs, which leads to the improvement of the quantum efficiency in the broadband of the solar spectrum.

“…Ag is cheaper than Au and presents an even stronger LSPR, making Ag nanoparticles good candidates for many different applications. They can be used for enhancing solar cell efficiency by means of light trapping in organic as well as inorganic solar cells [8,9] or they can be used together with TiO 2 to improve its photocatalytic activity. These nanoparticles produce an increased absorption in the visible region due to their aforementioned LSPR [10].…”

Silver nanostructured thin films have been fabricated on silicon substrate by combining simultaneously pulsed laser ablation in liquid (PLAL) and electrophoretic deposition (ED) techniques. The composition, topography, crystalline structure, surface topography, and optical properties of the obtained films have been studied by energy dispersive X-ray spectroscopy (EDS), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), and UV-visible spectrophotometry. The coatings were composed of Ag nanoparticles ranging from a few to hundred nm. The films exhibited homogenous morphology, uniform appearance, and a clear localized surface plasmon resonance (LSPR) around 400 nm.
