brighter/ more efficient LEDs: by connecting crystal structure directly to both efficiency/ advanced optical functionality minimizing energy dissipation from iodine vacancies... solar cells: improve stability/ power conversion efficiency by minimizing energy dissipation from iodine vacancies... spintronics/ quantum devices: achieve Rashba effect, exhibiting 2 subbands with opposite spin states, also benefited by resulting circularly polarized light emission... secure optical communication: also benefited"
