“…Recently light-trapping structures have been utilized in different ways to increase the absorption of plasmonic solar cells. Several structures including surface texturing [4][5][6], anti-reflection coatings [7,8], photonic crystals [9], nanogratings [10,11], and metallic nanoparticles [12][13] have been presented to enhance the absorption of plasmonic solar cells. Solar cells are generally classified into four generations [14][15][16][17][18].…”

In this paper, a plasmonic solar cell using silver nanoparticles is presented. The unit cell structure composes of two layers, each containing a silver nanoparticle deposited on the absorber layer and covered with an indium tin oxide layer. Nanoparticle structure has been used for light-trapping to increase the absorption of plasmonic solar cells. By various light trapping techniques, light can be concentrated in a thin absorber layer. As it will be clarified, through varying the geometry of these nanoparticle structures, the absorption peaks can be directed. All simulation data are obtained using the finite element method. The proposed model achieves two absorption peaks existing at 1.07 μm and 1.17 μm, each with absorptions of around 50%. The parameters of optimized performance have been specified. The results indicate that this model shows an absorption full width at half maximum, reaching 122 nm. Moreover, it can be noticed that the absorption peak can be increased to reach 0.5. The proposed structure has potential applications in the absorption of the infra-red part of the solar spectrum.

“…An asymmetric carrier-selective contact (CSC) design with a manufacturing process that can occur at a low temperature procedure, superior surface passivation, and extremely high efficiency is an alternative strategy that can be used to address these issues. [9][10][11][12] The SHJ solar cell structure, along with doped/intrinsic a-Si:H layers and c-Si layers, is a key limitation to achieving higher conversion efficiency using a low-temperature approach.

In silicon heterojunction (SHJ) solar cells, a wide bandgap material with a high work function is widely used as the hole extraction pathway to attain high efficiency. We introduced a molybdenum oxide (MoOx) film as an effective hole-transfer layer in carrier selective contact (CSC) solar cells by virtue of its wide bandgap along with high work function. The passivation characteristics, and optical and electrical properties of MoOx films were investigated by differing thickness and work function. The combination of 6 nm hydrogenated intrinsic amorphous silicon (a-Si:H(i)) and 7 nm thermally evaporated MoOx passivation layers provides excellent passivation properties, reduces carrier recombination, and improves the cell performance. The synthesized CSC solar cells showed promising results, with an open-circuit voltage (Voc) of 708 mV, short-circuit current (Jsc) = 37.38 mA/cm2, fill factor (FF) = 74.59%, and efficiency (η) = 19.75%. To justify the obtained result, an AFORS HET simulation was conducted based on the experimental results. The high work function and wide bandgap MoOx/c-Si(n) interface developed a considerable built-in potential and suppressed the electron–hole pair recombination mechanism. The CSC solar cell's simulated performance was enhanced from 1.62 to 23.32% by varying MoOx work function (ΦMoOx) from 4.5 to 5.7 eV.
