A comprehensive analysis of advanced solar panel productivity and efficiency through numerical models and emotional neural networks.

This study presents an in-depth analysis and evaluation of the performance of a standard 200 W solar cell, focusing on the energy and exergy aspects. A significant research gap exists in the comprehensive integration of numerical models with advanced machine-learning approaches, specifically emotional artificial neural networks (EANN), to simulate and optimize the electrical characteristics and efficiency of solar panels. To address this gap, a numerical model alongside a novel EANN was employed to simulate the system's electrical characteristics, including open-circuit voltage, short-circuit current, system resistances, maximum power point characteristics, and characteristic curves.

Synthesis of a novel nanomagnetic N bis schiff base complex of copper(ii) as an efficient catalyst for click synthesis of tetrazoles.

In this study, we have prepared a novel bis-Schiff-base copper(ii) complex by modifying FeO with acetylacetone functionalities and subsequently forming a Schiff base with 2-picolylamine and CuCl through a template method.
