چکیده:

An electrical model was established in spice, for simulation of CdTe thin-film PV cells. In this paper, an algorithm, based on Genetic algorithm, is introduced for determining circuit parameters. The measured i-v data of fabricated solar cell are used to match circuit model parameters. This method is an efficient way for accurate measurement of the lumped parameters of a solar cell such as series resistance, parallel resistance and leakage current of PN junction. This model can also be used for simulation of PV Modules and behavior of PV system.The importance of series resistance on efficiency and fill factor of the solar cell was revealed from sensitivity analyzes of this model. Fill factor is reduced by back contact effect that is considered.
