This program aims to recruit international students with academic backgrounds in materials science, chemical engineering, energy technology, or electrical engineering to join the research team. The internship duration ranges from 2 to 6 months, scheduled between April and December 2026, with flexibility depending on student availability and research progress. The training will cover perovskite and redox flow battery device fabrication, materials synthesis and characterization, electrochemical measurements, device performance evaluation, encapsulation and stability testing, as well as scientific writing. Participants will receive comprehensive theoretical and hands-on training, gaining practical experience in the development and integration of tandem perovskite solar cells and redox flow energy storage systems. This program is designed to strengthen participants’ knowledge and technical expertise in next-generation solar energy and energy storage technologies. The program provides a monthly stipend of NT$15,000. On-campus dormitory accommodation is available at a cost of NT$520 per week. Participants are responsible for their own meal expenses, as well as costs related to (i) health examinations, (ii) travel, (iii) visa applications, and (iv) insurance. Applicants must commit to a minimum duration of 2 months and a maximum of 6 months. Eligible applicants include current undergraduate, Master’s, or PhD students with relevant academic backgrounds. A basic ability to communicate in English is required.
