Most textbooks on Semiconductor Physies laek an introduction to the application of basie theories inproduction practice and research frontiers, lf teachers strictly follow the content of the textbook, it is notconducive to cultivating students' ability to analyze and solve practical problems.In view of this ,it takes erystalsilicon solar cells as an example to explain how to intersperse the application of basie theories in productionpraetice and research frontiers in the teaching process of “Semiconductor Physics" , in order to stimulate students’interest in learning, improve their enthusiasm and initiative, and thus improve the teachingeffectiveness of the corse.
