Abstract: Flexible perovskite device is the research hotspot of the flexible optoelectronic technology in the future. By employing 3D printing photopolymer technology, compatible manufacturing of flexible perovskite photoluminescent devices can be achieved. This research content is a forefront of interdisciplinary fields, covering professional knowledge in materials, polymers, chemistry, semiconductor physics, flexible electronics, and other related fields. In order to cultivate the innovative consciousness and scientific research thinking of undergraduates, and consolidate their professional theoretical knowledge and practical ability, we design an innovative experiment of fabricating flexible perovskite photoluminescent gels by 3D printing. The experiment involves 3D printing molding, post-processing of perovskite crystallization, characterization and analysis of experimental results, which allow students to personally participate in practice. While completing the whole process of preparing perovskite flexible devices independently, students can cultivate their scientific research interest and comprehensive ability to analyze and solve problems, so as to achieve the goal of innovative teaching experiments.
