Solar cells are capable of converting light energy into electrical energy and can completely replace the utilization of fossil fuel energy resources. The current research work majorly concentrates on the development and coating of antireflection materials over the front contact of silicon solar cells. Ferrous disulphide was one of the wide band gap semiconductors employed as a catalytic electrode (in DSSCs), counter electrode (in QDSSs), and solar energy harvester. FeS2 was synthesized through the hydrothermal method. The antireflective coating was performed over solar cells through the electrospraying technique. It was found that the antireflective material was distributed evenly over the coating substrate at 2 ml/h for 30 (F1), 60 (F2), 90 (F3), and 120 (F4) min. The coated solar cells were examined under neodymium light illumination mimicking sunlight. The effect of electrosprayed FeS2 films adhered over the front contact of solar cells was evaluated using various characterization techniques. The maximum efficiency attained by coated solar cells under indirect light was 19.6%. With the aid of electrospraying, hydrothermally synthesized FeS2 assists incoming photons with energy greater than the bandgap of a procured Si solar cell to take part in the photogeneration process. The maximum Isc and Voc of 38.08 mA/cm2 and 0.655 V were achieved for the F3 solar cell under neodymium irradiation.

“…The MoS2 sputter coating in 30 minutes solar cell was found to be uniform to other surface coatings. The minimum surface roughness coated sample experiences minimum incident light scattering which in turn resulting in maximum light transmittance [2]. This paves the way for attaining maximum solar cell performance.…”

“…Clean and green energy is quite necessary as it emits zero percent carbon dioxide to overcome global warming and the greenhouse effect [1]. Some of the unconventional renewable energy sources are geothermal energy, hydel energy, tidal energy, wind energy, solar energy, etc., Among those energies, solar energy is available abundant in nature and capable of satisfying future energy needs [2]. In recent years, many researchers were focussing on the performance enhancement of solar cells.…”

The current research focuses on sol-gel derived synthesis and RF sputter deposition of molybdenum disulphide (MoS2) over polycrystalline Si solar cell. Various coating layers were obtained under different sputter deposition at regular intervals. The influence of MoS2 sputter coating on optical, thermal chemical structural properties was examined through various characterisation techniques. 30 minutes coated solar cell reported maximum light transmittance of 95 % in the visible spectrum and minimum electrical resistivity of 2 × 10-3ohm-cm. 30 minutes coated solar cell exhibited maximum power conversion efficiency (PCE) of 19.19 % (open source) and 21.01 % (controlled source). Thermal imaging data reveal that the optimal coating layer experiences a minimum temperature of 33.9 °C and 49.9 °C. From experimental results, sputter deposited MoS2 Si solar cells experience minimum light reflectance and enhanced cell performance.

“…Mathematically signal and noise were known as mean and standard deviation of obtained experimental results. 15,16 It is a measure of characteristic quality of deviation from desired value. Depending on the required results, S/N ratios were classified as lower is better (LB), nominal is best (NB), or higher is better (HB).…”

Optimal lap geometry was considered for the analysis of fracture behavior in bolted composite joints. The test specimen comprising of composite laminated upper plate, aluminums lower plate and a protruding headed bolt. 1 An unidirectional fibered composite layers was considered for easier theoretical analysis. Based on nonlinear stress analysis, the selection of varying orientation especially for plies were performed. The system taken for analysis is depicted in figure and their corresponding dimensions represented in Table 1. A input file was initially created through ANSYS code for the creation of 3D model as specified before for simulation purpose. 2 Meshing was done before analyzing the 3D model. The 8-noded SOLID46 3-D ANSYS element was considered for modeling of required 3D model which is constrained in all directions. Basic 2D sketch of 3D object is depicted in Figure 1. With the usage of SOLID45 3-D ANSYS element, the modelling of composite plate and bolt was done. The contact between the surfaces in the required model were established through 3-D CONTAC49 ANSYS element. The properties of composite material in various directions are tabulated in Table 2.
