“…Depending on its crystallization arrangement, silicon can be classified as monocrystalline, polycrystalline, and amorphous. (2)(3)(4) The photovoltaic conversion efficiency of polycrystalline silicon has increased from 14-15% in the early days to more than 17%, whereas that of monocrystalline silicon has increased from 17% to more than 20%. The larger the frontal area of the chip that is exposed to light, the higher is its efficiency.…”

Solar energy is one of the most widely used green energy sources, but the consumption of chemicals during the manufacturing of solar panels lowers the environmental value of this source. Therefore, in this study, we apply wire electrical discharge machining to the edge insulation process of solar cell chips to avoid the disadvantages of using chemical edge insulation and reduce the cost of waste liquid disposal. In addition, process parameters, such as servo voltage, feed rate, machining depth, discharge gap, droplet flow rate, and the concentration of abrasive powder added, are investigated to improve the surface roughness of specimens, as well as to remove the phosphorus layer and minimize cracks on the specimen surface. The experimental results indicate that the surface roughness of silicon chips can be reduced from 0.614 to 0.365 µm using deionized water with a droplet flow rate of 12 cc/min at the servo voltage of 30 V, which resulted in a 40% improvement in the surface roughness of silicon chips. The addition of 0.6 g/l SiC to deionized water further reduced the surface roughness to 0.304 µm, which represented a 10% improvement over the value achieved with pure deionized water. This means that the need for a chemical post-treatment process can be reduced while maintaining the surface quality of the specimen and ensuring environmental protection. At the same time, the removal of the phosphorus layer and cracks in one single process pass demonstrates that wire electric discharge machining can be used efficiently for wafer edge insulation.

“…In the light interacted with plasmonic particles causes cumulative oscillations of the confined electrons in the NPs cause to modify the electrical field intensity around them which enhance the photo electron generations. Furthermore, the light trapped by scattering from the plasmonic nanoparticles inside the active layer causes to improve light absorption [6]. These nanoparticles properties can be tuned to harvest sun light at specific range of the spectrum.…”

Background: The quest for improving the efficiency of solar cells has garnered considerable attention in numerous scientific investigations. One promising approach involves utilizing plasmons generated by metal nanoparticles to enhance the performance of photovoltaic solar cells. Materials and Methods: High-purity gold nanoparticles (AuNPs), silver nanoparticles (AgNPs), and a combination of both were synthesized using pulsed laser ablation in distilled water. Subsequently, these nanoparticles were deposited onto silicon (Si) substrates and pre-existing Si homo-junction photovoltaic cells. Results: The optical analysis of the prepared nanoparticle suspension revealed distinct plasmonic bands located at approximately 400 nm and 523 nm wavelengths for AgNPs and AuNPs, respectively. In the case of the AuNPs:AgNPs mixture, two plasmonic bands were observed, corresponding to the presence of both types of metal nanoparticles. The X-ray diffraction (XRD) analysis of the deposited nanoparticle samples on Si wafers demonstrated a polycrystalline structure for all samples. Scanning electron microscopy (SEM) imaging displayed uniformly distributed spherical Au nanoparticles on the substrate, while AgNPs exhibited some aggregations. Conclusion: The photovoltaic (PV) solar cells demonstrated an enhanced performance, attributed to the ability of the plasmonic nanoparticles to facilitate increased light absorption or enhance surface conductivity. The combination of silver and gold particles holds promise for solar surface coating, further optimizing the cells to capture a greater amount of solar radiation within their plasmon peaks. This study highlights the potential of plasmonic nanoparticles to enhance the efficiency of previously prepared PV cells.

We propose a cross-shaped resonator design of a metamaterial (MTM) absorber that shows a 98% average absorbance in the range of 400–1100[Formula: see text]nm. This design consists of three layers: a tungsten-based cross-shaped on the top, silicon dioxide (SiO2) in the middle layer, and a tungsten layer at the bottom. The finite integration technique (FIT) method is used to simulate the metamaterial absorber’s performance. We have observed the absorber’s performance on the different thicknesses of a dielectric layer. We have presented the absorption spectrum for transverse electric (TE) and transverse magnetic (TM) modes for different polarization angles (0°–90°) and incident angles (0°–60°). Additionally, we have investigated the short-circuit current density for different dielectric layer thicknesses and different incidence angles. This is theoretically analogous to parametric studies. The universal AM 1.5 solar spectrum properties have been used to investigate the feasibility of the proposed MTM absorber as a solar cell. The proposed MTM has many potential uses, including for solar cells.
