Herein, we used TiO2 as the ETL and CBTS as the HTL in a CsPbI3-based PSC and optimized it using SCAPS-1D software, where the final optimization of the device gave a maximum PCE of 19.06%.

A comparative analysis along with the optimization of various parameters for 8 different Cs-halide perovskite absorber-based solar cells is performed using a SCAPS-1D simulator, where ZnO and CFTS are proposed as ETL and HTL materials, respectively.

Due to the consideration of less angle of attack in the Airfoil, the previous studies didn’t achieve accurate results on velocity and pressure of air fluid. Also, previous studies haven’t taken into account both the coefficients of drag and lift forces at the same time. In this study, first-time we used the NACA 4412 (national advisory committee for aeronautics 4412) Airfoil because of its availability, lightweight, and flat bottom surface which prevents negative ground effects. Here the NACA 4412 Airfoil surface characteristics were studied through ANSYS Fluent laminar flow analysis as well as pressure-based ANSYS fluent solver. When we increased the angle of attack from 0º to 18º the coefficients of lift and drag forces increase gradually, which impacts the values of the velocity of the upper surface and pressure of the lower surface in the air-fluid. The coefficient of lift and drag forces on the airfoil's surface were 0.44 and 0.5, while the velocity and pressure at the surface are 80.5354 ms^-1and 2.12 × 10^3 Pa respectively at a 16º angle.

The capability of temperature variation is essential for cooling industrial operations like transportation such as car and heavy vehicle radiators, electronics devices, petroleum industrial systems, etc. Different methods and fluids are used in the cooling process in industrial systems. The basic fluids are based on temperature, thermal stability, and the effectiveness of heat transmission. Thermal characteristics improve when nanoparticles are added to the basic fluid. Using Al_2O_3 nanofluid the heat transfer and variation in the temperature at the entrance side and outlet side of the micro-channel pipe were studied. Through ANSYS Fluent, a well-defined method for utilizing Al_2O_3 nanofluids to investigate the impact of various performance optimization factors of nanofluids was performed. The temperature of the nanofluids at the inlet and outlet is found 300 K and 313.7 K, respectively during the simulation. The pressure drops from the inlet side to the outlet side as well a result that raising the temperature, heat coefficient, thermal conductivity, and viscosity of the base fluids when Al_2O_3 nanoparticles are added.

During the operation of lithium-ion batteries, unexpected heat could be generated, which reduces the energy storage capacity as well as the longevity of the batteries. A unique cooling strategy involving an oscillating heat pipe is suggested as a solution to this study. The cooling channel is mounted on the outside of the battery module since electric vehicles have a little amount of space. This work used ANSYS/Fluent to build a lithium-ion battery model for a rectangular cell and evaluate its performance using the cooling system on the battery cell. The heat generated in the flow direction was absorbed by air-fluid throughout the cooling process, which decreased the cooling capacity. The temperature downstream is therefore always higher than the temperature upstream. In this process, the temperature varies from 288 K to 292 K. . In this study, the temperature of the battery rises quickly in the absence of a cooling system while rising gradually in the presence of one. As a result, the cooling system helped to provide a better outcome.

This study aimed to investigate a techno-economic evaluation of the photovoltaic system, along with a diesel generator as a backup supply, to ensure a continuous twenty-four hours power supply per day, no matter the status of the weather. Healthcare centers in Bangladesh play a vital role in the health issues of the residents of rural areas. In this regard, a healthcare center in Baliadangi—Lahiri Hat Rd, Baliadangi, Thakurgaon, Bangladesh, was selected to be electrically empowered. The simulation software Hybrid Optimisation Model for Electric Renewables (HOMER) and the HOMER Powering Health tool were used to analyze and optimize the renewable energy required by the healthcare center. It was found that the healthcare center required a 24.3 kW solar PV system with a net current cost of $28,705.2; the levelized cost of electricity (LCOE) was $0.02728 per kW-hours, where renewable energy would provide 98% of the system’s total power requirements. The generator would provide 1% and the grid would supply the remaining 1%. The load analysis revealed that the hybrid PV system might be superior to other power sources for providing electricity for both the normal function and the emergencies that arise in healthcare’s day-to-day life. The outcome of the study is expected to be beneficial for both government and other stakeholders in decision-making.
