Simulation of current-voltage characteristics and power-voltage characteristics of "space" solar cells based porous silicon in the Comsol Multiphysics package

Abstract

To analyze the characteristics of solar modules based on porous silicon involved in the flight experiment aboard a small spacecraft AIST 2D, the method of computer simulation of solar cell characteristics was used. The paper presents the procedure for developing a simulation model of photovoltaic modules in Comsol Multyphysics. The developed model allows us to investigate the current-voltage and voltage-watt characteristics of solar modules and determine the main parameters. The discrepancy between the experimental data obtained from the telemetry data from the AIST-2D with the simulation results does not exceed 5%.
