This work addresses the instability and toxicity issues related to lead halide perovskite solar cells (PSCs) by introducing a stable and lead-free BiFeO3 (BFO) as perovskite absorber. Furthermore, it initially builds on an earlier published experimental BFO solar cell (SC). The mathematical models were validated by calibrating the simulated J-V curve with the experimental curve. Subsequently, novel material design and optimisation strategies were adopted to improve the efficiency in BFO.BFO PSCs, utilizing a variety of electron transport layers (ETLs) like ZnO, TiO2, C60, ZnS, PCBM and hole transport layers (HTLs) such as NiO, Cu2O, P3HT, PEDOT: PSS, and Spiro-OMeTAD were modelled numerically using SETFOS 5.3 software. An extensive analysis was conducted to determine the optimum thicknesses, doping densities of the active layer, ETLs, and HTLs. Additionally, the effects of the defects in the absorber, series and shunt resistance, various electrodes, and working temperature on device efficiency were investigated. After thorough optimization, the PV device with configuration FTO/ZnO/BiFeO3/Cu2O/Au demonstrates the highest performance.

The system specifically targets the detection of four prevalent casting defects: blowholes, pinholes, shrinkage, and hot tears. The study introduces an innovative methodology that enhances model performance by segmenting the original image into smaller sub-parts and deploying multiple labeling techniques. This approach has been designed to capture intricate defect patterns often overlooked in conventional systems. The resultant model achieves a remarkable classification accuracy of 97.6%, as verified by a test dataset.

Structural analyses demonstrated that undoped US-Pd/C contained crystalline and uniformly dispersed Pd nanoparticles, while 1 wt.% Sr doping reduced crystallite size and introduced structural distortions that enhanced defect sites and electronic interactions. In contrast, 3 wt.% Sr led to particle agglomeration, porosity loss, and decreased accessibility of active sites, as confirmed by SEM, TEM, and EDX analyses. Electrochemical measurements revealed that the US-PdSr/C catalyst with 1 wt.% Sr exhibited a lower Tafel slope (0.24 V/dec), higher mass activity (1838 mA/mg), reduced ohmic resistance (~ 0.0029 Ωcm2), and superior power density (59.4 mW/cm2) compared to conventionally synthesized Pd/C. Polarization curves demonstrated notable improvements in both activation and ohmic regions, while a lower overpotential (0.51 V) indicated enhanced energy conversion efficiency.

Such behavior greatly supported the CA6 grains to grew along the direction perpendicular to the basal plane and was responsible for a more equiaxed morphology and highly dense microstructure with improved mechanical properties and thermal shock resistance. Moreover, reduction of apparent porosity and improvement of wettability inhibit the penetration and adhesion of molten steel on the material surface, thus achieving the improvement in corrosion resistance of molten steel.
