Abstract:A new optimization algorithm, GA-AFSA, was proposed by integrating Genetic Algorithm (GA) and Artificial Fish Swarm Algorithm (AFSA) to fit for the mathematic model of I-V curve of solar cell. It maintained the global optimization advantages of GA and quick convergence of AFSA while overcoming the defects of GA's slow convergence and AFSA's stepping without a definite purpose. By fitting the five important parameters of I-V curve, namely the photo-generated current of solar cell, quality factor of diode, series resistance, reverse saturation current and shunt resistance, GA-AFSA made a great improvement. Compared with the existing algorithm, the new one has a higher precision and a rapid convergence speed.
