A New Practice of “Production Line Collaboration + Process Linkage” Optimization Model for Solar Cell Production Lines

Driven by the dual-carbon strategic goal, the solar cell industry has developed rapidly, while production efficiency, line balance, and quality control have become increasingly prominent engineering issues. As solar cells convert incident electromagnetic radiation into electrical energy, stable and efficient production-line management is directly related to photovoltaic device performance and clean-energy supply. This paper takes the solar cell production line as the research object and systematically explores an optimization model based on production-line collaboration and process linkage. The development background of the photovoltaic industry and the pain points of traditional production management are reviewed, and the core connotation and theoretical basis of the model are clarified. Implementation paths are proposed from three aspects: cross-process data interconnection, process-cycle matching and bottleneck optimization, and a closed-loop quality traceability system. Practical results show that the model improves the balance rate of the production line, shortens the production cycle, reduces process waiting waste, and supports the transformation of solar cell manufacturing toward digitalization and intelligence. The research provides a reference for high-quality development of photovoltaic and electromagnetic-energy conversion industries.
