MATLAB Implementation of Photovoltaic Cell Model

To better understand and utilize photovoltaic cells, studying existing models and their practical applications is essential. This implementation references a photovoltaic cell model from a Southwest Jiaotong University master's thesis, providing a comprehensive framework for building and testing photovoltaic systems. The MATLAB code incorporates key functions for parameter initialization, current-voltage (IV) characteristic calculations, and power output simulations.

The model enables researchers to explore various material properties, cell configurations, and operational conditions through configurable parameters including light-generated current, diode saturation current, series resistance, and temperature coefficients. The core algorithm solves the photovoltaic cell's implicit current equation using iterative methods like Newton-Raphson to ensure accurate IV curve generation.

Key implemented functions include: - CellParameterSetup() for defining physical constants and environmental variables - CalculateIVCurve() implementing the single-diode model equation with shunt resistance consideration - PlotCharacteristics() for visualizing PV cell performance under different irradiance and temperature conditions - EfficiencyCalculation() for evaluating energy conversion performance

Through examination and experimentation with this model, engineers can gain valuable insights into photovoltaic cell behavior, performance optimization, and contribute to developing more efficient solar energy technologies. The code structure allows easy modification for studying novel materials, multi-junction cells, and partial shading effects.
