摘要:

以钙钛矿太阳能电池为切入点,针对传统能源与新能源课程中电子传输层材料的教学内容,将化学浴沉积法(CBD)制备二氧化锡电子传输层这一前沿成果融入教学实践。 采用扫描电子显微镜(SEM)、X射线衍射(XRD)和荧光光谱(PL)等手段对CBD法制备的二氧化锡薄膜进行表征分析,并将其应用于钙钛矿太阳能电池的制备,评估其对器件性能的影响。 结果表明,与传统旋涂法相比,CBD法制备的二氧化锡薄膜更加均匀致密,具有更好的结晶度和更高的电子提取能力,可以获得更高的器件效率。 该研究构建了“理论-实践-探究-创新”的教学模式,通过设计CBD法制备二氧化锡电子传输层的教学实验,可以有效提升学生的学习兴趣,加深他们对理论知识的理解,并激发了他们在新能源领域的探索热情。 为高校新能源材料与器件专业的本科生实验教学改革提供新的思路,并对培养具备实践能力和创新精神的新能源人才提供借鉴。

Abstract:

This study focuses on the teaching of electron transport layer materials within the Traditional Energy and New Energy curriculum, using perovskite solar cells as a starting point. It integrates the cutting-edge research on chemical bath deposition (CBD) of tin oxide (SnO2) electron transport layers into teaching practice. The study employs scanning electron microscopy (SEM), X-ray diffraction (XRD) and photoluminescence spectroscopy (PL) to characterize the SnO2 thin films prepared by CBD. It then applies these films to fabricate perovskite solar cells, evaluating their impact on device performance. The results show that compared to SnO2 thin films prepared by the traditional spin-coating method, those prepared by CBD are more uniform and denser, exhibit better crystallinity and higher electron extraction capability, ultimately achieving higher device efficiency. This research constructs a “Theory-Practice-Inquiry-Innovation” teaching model. By designing a teaching experiment on CBD of SnO2 electron transport layers, it effectively enhances students' learning interest, deepens their understanding of theoretical knowledge and stimulates their enthusiasm for exploring the field of new energy. This research provides a new approach for experimental teaching reform in universities and holds significant importance for cultivating new energy talents with practical skills and an innovative spirit.
