Simulated device structures of type A and B OLEDs. The grating attenuation shown in Figure 1 is taken into account in the model. The air and glass layer thicknesses are not to scale. Their thickness in the simulation is 1 μm to keep the perfectly matched layers (PMLs) at a distance from the near fields around the nanostructures. The plane wave sources necessary for the reciprocity‐based simulation are placed a few mesh cells above the bottom PML. 2D field monitors are placed on the F8BT/MEH‐PPV layers.

Over the past decade, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has experienced a remarkable ascent, soaring from 3.8% in 2009 to a remarkable record of 26.1% in 2023. Many recent approaches for improving PSC performance employ nanophotonic technologies, from light harvesting and thermal management to the manipulation of charge carrier dynamics. Plasmonic nanoparticles and arrayed dielectric nanostructures have been applied to tailor the light absorption, scattering, and conversion, as well as the heat dissipation within PSCs to improve their PCE and operational stability. In this review, it is begin with a concise introduction to define the realm of nanophotonics by focusing on the nanoscale interactions between light and surface plasmons or dielectric photonic structures. Prevailing strategies that utilize resonance‐enhanced light–matter interactions for boosting the PCE and stability of PSCs from light trapping, carrier transportation, and thermal management perspectives are then elaborated, and the resultant practical applications, such as semitransparent photovoltaics, colored PSCs, and smart perovskite windows are discussed. Finally, the state‐of‐the‐art nanophotonic paradigms in PSCs are reviewed, and the benefits of these approaches in improving the aesthetic effects and energy‐saving character of PSC‐integrated buildings are highlighted.
