Solar Cell Parameter Identification Using Genetic Algorithms

Abstract

The equation of the external voltage-current characteristic I(V) of a solar cell is determined using genetic algorithms based on isolated points of the characteristic obtained experimentally. The equation represents a mathematical model with 7 parameters. Calculating fitness requires simulation on this model. To do this a MATLAB-Simulink model was developed. All calculations associated to process the genetic algorithms are integrated into one program, with very good convergence.
