Recent advancements in metal/perovskite photodetectors have leveraged plasmonic effects to enhance the efficiency of photogenerated carrier separation. In this work, we present an innovative approach designing heterostructure that involved integrating a perovskite film with metasurface. Using finite-difference time-domain (FDTD) simulations, investigated formation hybrid photonic–plasmonic modes and examined their quality factors relation loss mechanisms. Our results demonstrate these facilitated strong light confinement within layer, significant intensity enhancement at metal–perovskite interface—an ideal condition for efficient charge generation. We also propose use low-bandgap perovskites direct infrared passive detection explore potential highly Stokes-shifted active applications, including ultraviolet X-ray radiation.
