Renewable Energy Experiment and Teaching Innovation: Experimental Teaching Mode of Solar Cell Manufacturing Process Based on PV Factory

The development of renewable energy can not be separated from the teaching innovation of experimental courses of energy specialty. The preparation technology of large solar energy batteries is a required course for students majoring in new energy, which has the characteristics of experiment and application. However, the shortage of experimental resources and experimental funds make it impossible for many students to start the experiment. In order to solve this problem, based on the PV Factory simulation software, this paper simulates the production process of the aluminum backfield p-type battery sheet in industry, and innovatively designs the experimental teaching mode of solar cell preparation. In the experimental teaching mode of this paper, the students simulate the preparation steps of solar cells through the PV Factory simulation software. In practice, the PV Factory simulation software will refine the solar cell preparation process to 12 small steps, 28 physical and chemical reactions, and 24 process parameters. Students can design and generate solar cells by adjusting the parameters of each response. On the one hand, it is the first time to use software to simulate the preparation of solar cells and use it in the experimental courses of College students, which creatively solves the problems of shortage of experimental resources and insufficient learning time. On the other hand, the experimental method creatively restores the whole process of solar cell preparation, resolves the problem that theoretical knowledge learning and experimental operation are not synchronized in the experimental teaching, and promotes students' deep understanding of the whole process of solar cell preparation. The experimental teaching mode designed in this paper can also train students' good scientific literacy through a variety of parameter settings, rigorous experimental simulation process, exercise their problem solving ability.
