Multiple quantum well solar cells (MQWSC) enhance the absorption of sunlight by allowing tunable bandgaps and improved carrier collection. This design aims to increase overall solar cell efficiency by optimizing energy conversion processes. Surficial photonic design is another approach to provide roughness which prevents reflection of sunlight from the solar cell surface and increases the optical paths of photons to reach the absorber layer. This article is focused on determining sui TableIII-V materials with structure configurations to implement in quantum wells to maximize efficiency beyond the fundamental p-n junction solar cells. Also, surficial circular nanoholes were considered to be implemented for maximizing light absorption. A total of six reported III-V semiconductor materials InP, InGaP, AlGaAs, GaSb, InGaAs, and InGaN were considered to be implemented on quantum wells. 5 layers and 25 layers of arrangements of each III-V material were investigated. Finally, the highest-performing MQWSC was incorporated with the optimized surficial nanostructure design, and the structure's performance was compared with a fundamental single junction solar cell. GaAs solar cell is considered in this study as the host structure to implement quantum wells and surficial structure. Optical simulation was conducted to investigate light trapping enhancement using the Ansys Lumerical FDTD software. GaAs solar cells with a single junction as well as MQWSC were examined using the Ansys Lumerical CHARGE solver. It was found that the 25 layers of InP/GaAs MQWSC obtained the highest efficiency among all six III-V materials and their two physical combinations. Finally, the surficial circular nanohole design was incorporated with the highest efficient multiple-quantum well combination to obtain electrical results. The analysis shows that the 25 layers of InP/GaAs MQWSC with circular nanoholes improve the efficiency significantly from fundamental single junction GaAs solar cells. Other el

Owing to their severity and widespread incidence, which result in large crop losses, jute pests are regarded as the main issue for agricultural output. Soft computing techniques can be used to protect crops from hazardous pests, which is important for increasing agricultural yield. The deep learning (DL) and conventional machine learning (ML) methodologies serve as the foundation for soft computing solutions. However, DL approaches are computationally expensive and require a huge quantity of training data. In contrast, the selection of manual feature extraction processes in standard methods is inefficient, time-consuming, and unsuccessful. This research presents an effective approach for detecting pests using a jute that accurately classifies the bugs and visualizes them based on the specified class label by Shapley Additive Explanations (SHAP). In the proposed work, we proposed a Lightweight CNN model. Experimental results demonstrate that it achieved 99.43 % accuracy outperforming existing state-of-the-art (SOTA) models. The paper further focuses on the interpretability aspect by employing SHAP visualizations, shedding light on the key features influencing model predictions and thus enhancing transparency in decision-making. The end-to-end integration with Gradio not only amplifies the model's utility but also facilitates broader accessibility, allowing stakeholders to engage with the technology in real time. We compare the suggested model's results with those of numerous SOTA models to assess the model's efficacy;the suggested model produced the best outcomes in the experiments. We created the suggested model end-to-end using Gradio since it has the potential to be used in practical settings. This will encourage more studies on pest identification to boost agricultural output. © 2024 IEEE.

Thallium (Tl)-based halide perovskites have developed as a hopeful candidate for various optoelectronic uses including solar cells, LEDs, photodetectors, etc. for their distinctive optical and electrical properties. TlMCl3 (M=Ca, Cd) are studied under the force of hydrostatics differing from 0 to 125 GPa and 0 to 200 GPa utilizing first-principles methods. The bandgap of TlCaCl3 reduced from 3.953 eV to 1.924 eV under variation in pressures between 0 and 125 GPa causing an UV to visible area transition. The bandgap of TlCdCl3 is reduced from 1.789 to 0 eV via changing pressure from 0 GPa to 200 GPa and the compound became metallic at 200 GPa. An increasing tendency of optical absorptivity, conductivity, and reflectivity is observed in both compounds under pressure. Both compounds are mechanically stable, and the ductility also increases with the applied pressure. © 2024 IEEE.

Forecasting electricity load is essential to the effective administration and functioning of power systems. This paper investigates the efficacy of various ensemble methods in Short-Term Load Forecasting (STLF) using a real-world dataset. We explore the implementation and comparative performance of four advanced ensemble models: Random Forest (RF) with Extra Trees Regressor (ETR), RF with XGBoost (XGB), XGB with ETR, and a Voting Regressor combining all aforementioned models. Our study focuses on developing these models, preprocessing data, and meticulously tuning parameters to optimize forecasting accuracy and robustness. The models are evaluated using different precision matrices such as R2, Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE). The Voting Regressor model exhibited the best performance in this work, as indicated by their low RMSE and MAE values and high R2 scores. © 2024 IEEE.

The world is currently undergoing the fourth Industrial Revolution (4IR), in which information plays a crucial role in everyday life. However, those with visual impairments are unable to access information by visual means. Approximately 237 million individuals worldwide suffer from vision impairment. The Refreshable Braille Display (RBD) is considered the most advanced and significant instructional tool for the visually impaired (VI), garnering interest from scientists and researchers worldwide. There are numerous technologies available to actuate the RBD. A comprehensive and meticulous examination of the existing technologies is necessary to make the proper choice of actuating technology in relevant applications. This paper aims to categorize the published articles based on the different types of actuation technologies that exist, and to examine each technology in terms of its benefits, drawbacks, and technical and economic parameters such as cost, power consumption, frequency, durability, etc. The analysis demonstrated that the electromagnetic actuation method is the most suitable approach from both an economic and technical standpoint. The authors proposed a RBD that utilizes the electromagnetic actuation approach. This method involves the use of a permanent magnet, electromagnet, and a cam in each braille pin. The proposed method is anticipated to fulfill all the necessary criteria and specifications of a braille display. The authors have already finished creating the computer-aided design (CAD) model of the proposed approach. © 2024 IEEE.

Due to rapid urbanization and increasing energy use, Bangladesh is facing challenges in ensuring a reliable electricity supply, therefore it makes sensible to use more renewable resources in order to meet the rising energy demand. This research develops an energy management system (EMS) with two different approaches based on the facilities of various types of consumers. One approach uses renewable energy resource (RER) and energy storage system (ESS) with block rate tariff. Based on the state of charge (SOC) of the ESS and the availability of solar energy, this optimization system schedules energy resources, decides when to use or turn off the grid. Then the optimization problem is resolved using Interior-Point method. Another approach is load scheduling based on time-of-use tariff without utilizing of ESS and RER, solved by applying Genetic Algorithm. All of these methods are simulated in MATLAB. The optimization results are compared with the real-time electricity bills to confirm validate the model. It is shown that the simulation result of block rate tariff model using RER and ESS is more effective which reduces electricity costs by 68.97% and usages of grid energy by 75.23% than the load scheduling model. © 2024 IEEE.
