Research on Modeling and Simulation of Cd-Te Thin Film Solar Photovoltaic Cells

This paper simulates the relationship between the output characteristic curve of CdTe thin film solar cells and the changes of ambient light intensity and ambient temperature in the actual application process. On the basis of the equivalent circuit of CdTe thin film solar cell, the engineering mathematical model is established with the simulation parameters of the solar cell module provided by the CdTe battery manufacturer. According to the engineering mathematical model of the CdTe thin film solar cell, the model is built and simulated in the Matlab/Simulink simulation system to simulate the gradual change of the light intensity when the temperature is constant and the gradual change of the ambient temperature when the light intensity is constant, and observe the I-V P-V output characteristic curve, analyze the relationship between CdTe thin film solar cell and external light intensity and ambient temperature.
