Description

technical field [0001] The invention belongs to the field of photovoltaic cells, and in particular relates to a method for building a photovoltaic cell model. Background technique [0002] The development of photovoltaic cells and modules is becoming more and more complex, and the circuit forms of modules are also diversified. It is particularly important to predict the output characteristics of modules in advance and select the optimal design scheme. The traditional method needs to carry out the actual measurement and comparative analysis of various batteries or components to determine the optimal design scheme. This method has a huge workload and laborious consumables, which not only increases the workload of the R&D personnel but also slows down the R&D progress. [0003] Using simulation software to model and simulate batteries and component circuits can easily, quickly and accurately analyze the output electrical characteristics of batteries and components, which can n...
