摘　　要：随着能源需求日益增加,开发利用新能源成了当下任务。硫化铅胶体量子点太阳能电池的性能一直因为传输层界面的缺陷而受到影响。通常,1,2-乙二硫醇(EDT)作为硫化铅胶体量子点太阳能电池中的空穴传输层。然而,配体交换过程中的快速反应使得空穴传输层薄膜中易产生裂纹,导致性能降低。因此,文章在理论授课基础上,通过设计实验,将乙酸乙酯加入乙腈溶液中,有效减慢配体交换的速度,并基于此制备出高质量的空穴传输层薄膜。让学生更加深入了解量子点材料在光伏领域内的重要作用,学以致用,将科研知识融入本科教学,提升了学生思维与动手能力。With the increasing demand of energy,the development and utilization of new energy sources have become an immediate task.The performance of lead sulfide colloidal quantum dot solar cells has always been impeded by the interface defects of transport layer.Commonly,1,2-ethanedithiol(EDT)serves as the hole transport layer in lead sulfide colloidal quantum dot solar cells.Nevertheless,the rapid reaction during the ligand exchange process tends to generate cracks in the hole transport layer film,resulting in decreased performance.Hence,this paper designs experiments by adding ethyl acetate to the acetonitrile solution,effectively slow down the ligand exchange rate,preparing high-quality hole transport layer film.This enables students to gain a deeper understanding of the significant role of quantum dot materials in the photovoltaic field,and incorporate scientific knowledge into undergraduate teaching,enhancing their thinking and practical abilities.
