A multilayer perceptron neural network approach for optimizing solar irradiance forecasting in Central Africa with meteorological insights

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Feb. 12, 2024

Abstract Promoting renewable energy sources, particularly in the solar industry, has potential to address shortfall Central Africa. Nevertheless, a difficulty occurs due erratic characteristics of irradiance data, which is influenced by climatic fluctuations and challenging regulate. The current investigation focuses on predicting an inclined surface, taking into consideration impact variables such as temperature, wind speed, humidity, air pressure. used methodology for this objective Artificial Neural Network (ANN), inquiry carried out metropolitan region Douala. data collection device research meteorological station located at IUT This was built component Douala sustainable city effort, partnership with CUD IRD. Data collected 30-min intervals duration around 2 years, namely from January 17, 2019, October 30, 2020. aforementioned been saved database that underwent pre-processing Excel later employed MATLAB creation artificial neural network model. 80% available utilized training network, 15% allotted validation, remaining 5% testing. Different combinations input were evaluated ascertain their individual degrees accuracy. logistic Sigmoid function, 50 hidden layer neurons, yielded correlation coefficient 98.883% between observed estimated sun irradiation. function suggested evaluating intensities radiation place being researched other sites have similar conditions.

A Density Functional Theory Exploration of Cs₂B′B″I₆ (B′B″: BeCa, BeSr, GeCd, GeBe, GeMg) Halide Double Perovskites for Optimal Solar Cell and Renewable Energy Applications

physica status solidi (b), Journal Year: 2024, Volume and Issue: 261(6)

Published: April 15, 2024

A comprehensive investigation into the structural, elastic, optoelectronic, and thermoelectric properties of Cs 2 B′B″I 6 halide double perovskites (DPs), where B′B″ represents various combinations, including BeCa, BeSr, GeCd, GeBe, GeMg, is conducted. Using full‐potential linearized augmented plane wave approach within density functional theory framework, this analysis confirms materials’ structural dynamic stabilities through negative formation energies adherence to elastic constant stability criteria. The generalized gradient approximation modified Becke–Johnson (mBJ) potential for electronic structure calculations are utilized. Notably, DPs with as BeCa or BeSr exhibit direct bandgaps (Γ–Γ), while those GeMg display indirect (X–L). These findings offer valuable insights use these materials in photovoltaic optoelectronic devices. Furthermore, exploration properties, covering electrical conductivity, Seebeck coefficient, thermal figure merit at temperatures 300, 600, 900 K, suggests that DPs, regardless specific composition (BeCa, GeMg), holds promise applications
