City University of Hong Kong is recruiting a Postdoctoral Fellow and PhD student in perovskite solar cells and advanced chiral optoelectronic devices . The postdoctoral project focuses on perovskite thin-film crystallisation, interface and defect engineering, ion migration, operational stability, chiral functional materials, and emerging optoelectronic devices. The group is especially interested in candidates with hands-on experience in perovskite device fabrication, device optimisation, and advanced materials/optoelectronic characterisation. Preferred technical background includes solution processing, thin-film deposition, thermal evaporation, glovebox operation, photovoltaic device fabrication, and characterization methods such as XRD, SEM, AFM, XPS, UV-vis absorption, photoluminescence, electrochemical measurements, impedance spectroscopy, transient optoelectronic characterization, and stability testing. The postdoctoral salary is HKD 25,000–30,000 per month, depending on qualifications and experience. Outstanding candidates may be nominated for competitive fellowship schemes such as the RGC Junior Research Fellow Scheme and the Jockey Club STEM Early Career Research Fellowship . The PhD opening is for 2027 Fall admission in the research group. The project interests include asymmetry-related materials such as chirality, adaptive materials, and advanced optoelectronic devices including solar cells, LEDs, and memristors. Applicants should have a Bachelor’s or Master’s degree in a relevant field, strong motivation, and a solid experimental background. English requirements listed are TOEFL 79, IELTS 6.5, or CET-6 490. PhD funding may come through the Hong Kong PhD Fellowship Scheme (annual stipend HKD 337,200 plus HKD 14,000 travel allowance for 4 years) or the CityUHK Postgraduate Studentship (monthly stipend HKD 19,100–19,600 for 4 years, plus possible conference travel support). To apply, email your CV and a short statement of interest to [email protected] . The full advertisement is available on the lab website.
