基于Quokka软件的太阳能电池结构设计实验教学创新

Experimental teaching innovation of solar cell structure design based on Quokka software

太阳能电池结构设计的课程偏重于实践和应用,但由于一般高校实验室缺乏必要的实验设备,该实验教学部分很难实现。因此,设计了基于Quokka模拟软件的仿真实验教学,以背接触IBC电池结构为例,给出了实验教学的过程,该实验设计准确度高,贴近实际电池片设计的开发流程,仿真速度快,不需要借助超级电脑就能实现大量的仿真对比。此外,该实验教学方法简明扼要、可操作性强,方便学生在课余时间练习。通过该实验,学生可以把电池结构的各个组成部分联系到一起,不需要进入有危险化学品的实验室,就能对电池结构有一个整体的概念,通过灵活改变电池的结构设计,加深了学生对理论知识的理解与应用,提高了学生的学习、实践与创新能力。

The course of solar cell structure design focuses on practice and application. However, due to the lack of necessary experimental equipment in most of university laboratories, the experimental teaching part is difficult to achieve. Therefore, the simulation experiment based on Quokka simulation software is designed. By taking the back contact IBC solar cell structure as an example, the experiment teaching process is presented. This experiment design has high accuracy, close to the development process of the actual solar cell design, and the simulation speed is fast. Without the help of supercomputer, a large number of simulation comparisons can be achieved. In addition, the experimental teaching method is concise, practical and convenient for students to practice in their spare time. Through this experiment, students can obtain comprehensive understanding of the whole cell structure. Without entering the laboratory with dangerous chemicals, they can get an overall concept of the cell structure. By flexibly changing the structure design of the cell, students can deepen their understanding and application of theoretical knowledge, and improve their learning, practice and innovation abilities.
