space solar power station adopts large-area solar arrays for efficient photovoltaic conversion,making it one of the best solutions to future energy ***-orbit failure of solar arrays can affect the service life of spacecraft,thereby it is crucial to comprehend the impact of solar cell failure on the electrical performance of solar arrays and propose appropriate circuit design *** root cause of solar array failure is the degeneration of solar *** this paper,power loss caused by an open circuit or short circuit failure of solar cells in pure parallel and series–parallel circuits is described,and it reveals that an open circuit of the cell is more harmful in the pure parallel circuit,while a short circuit in the series–parallel circuit is more detrimental,which causes loss of electrical performance in series and parallel units,*** conclusions have been validated through model calculations and corresponding *** electrical loss is also influenced by the control *** the Maximum Power Point Tracking control mode favored by space solar power station,which can significantly increase generated power,application suggestions have been proposed based on the results of cell failure *** research will provide a reference for circuit selection and boundary design for solar arrays,reducing the probability of solar array failure and saving the manufacturing and redeployment costs of space solar power station.
