Abstract
This letter presents novel approximate analytical solutions for modeling solar cells’ current–voltage (I–V) characteristics by applying resistance–diode (RD) circuit approaches. Three different approximation methods are developed and used to modified solar cell equivalent circuits, including single, double, and triple-diode configurations. The proposed solutions demonstrate excellent agreement with numerical simulations and experimental measurements, while achieving significant reductions in computational time. These features make the methods suitable for real-time applications in power electronics and smart grid environments. The approach provides a valuable analytical tool for enhancing photovoltaic modeling and strengthens the connection between circuit theory and solar energy systems.
期刊介绍：
he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered.
In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
