[Abstract]:Under the environment of encouraging and supporting the development of new energy sources, the solar photovoltaic industry has been growing rapidly, and the solar cell industry has also developed rapidly with the development of the photovoltaic industry, and photovoltaic glass is one of the raw materials for solar cells. It is also an important part of the photovoltaic industry. When photovoltaic glass products are produced by Calendering method, the glass is prone to crack, bubble, deformation and other quality defects, even crystallization will occur, which seriously affects the transmittance and strength of photovoltaic glass. In this paper, the finite element MSC.Marc software is used to simulate the complex heat transfer problems in the calendering process of glass, and the variation of temperature in the calendering process of glass is analyzed and studied. At the same time, the function of MSC.Marc software was redeveloped to simulate the change of microstructure in glass molding and to study the change of glass crystallization. It provides the basis for optimizing the process parameters and deepening the research of glass crystallization theory, and has important theoretical value and practical significance for improving the quality of photovoltaic glass products. In this paper, a series of research work has been carried out in view of the above problems. In this paper, the calendering process and crystallization behavior of photovoltaic glass are numerically simulated and experimentally studied. Firstly, the research status of glass forming is briefly summarized, the basic process of photovoltaic glass calendering and the basic theory and method used in the finite element simulation of glass calendering are introduced. Based on the basic theory of heat transfer, based on the complexity of photovoltaic glass calendering process, the glass forming process is hypothesized, and the 3D mathematical model of glass calendering process is established. The relevant data of glass molding are set into the solution model, and the distribution of temperature field in the process of glass forming is simulated and analyzed. The influence of different roller temperature on glass forming was simulated under the same technological conditions. Secondly, based on the crystallization theory of glass and Uman model of crystallization, a two-dimensional model is established. By using the secondary development function of MSC.Marc software, the related development environment is set up, and the code program of glass crystallization is compiled with Fortran language. The open interface subprogram of MSC.Marc software is developed to simulate and analyze the crystallization behavior of glass during calendering. The temperature range of glass crystallization is inferred, and the change of glass microstructure is visualized. This is of great significance for the further study of the microstructure of photovoltaic glass. Finally, an experimental method is developed to detect the surface temperature of glass strip in the molding process by using temperature measurement tools, and the simulation results are verified by experiments to verify the reasonableness and correctness of the heat transfer problem of the simulated glass.
