前沿科技赋能传统能源与新能源教学:化学浴沉积法制备二氧化锡电子传输层

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.
