biostudies-literatureUnknown14(1)Rahimi SThe external quantum efficiency (EQE) of a perovskite-based light-emitting diode (PELED) is a key indicator, comprising the internal quantum efficiency (IQE) and light extraction efficiency (LEE). Currently, enhancing EQE faces a major challenge in optimizing LEE. This study introduces an innovative structure to boost LEE, exploring various influencing parameters. The transition from a planar to a domical architecture leverages factors like the waveguiding effect, resulting in a remarkable tenfold increase in LEE, from 6 to 59%. Additionally, investigations into factors affecting LEE, such as altering dipole orientation, material-substrate contact angle, and layer thickness, reveal the potential for further improvement. The optimized structure attains an impressive LEE value of 74%.Scientific reports5500https://www.ebi.ac.uk/biostudies/studies/S-EPMC10918065biostudies-literatureNew nanostructure perovskite-based light-emitting diode with superior light extraction efficiency enhancement.PMC10918065Rahimi SFathi DEskandari MfalseNew nanostructure perovskite-based light-emitting diode with superior light extraction efficiency enhancement.The external quantum efficiency (EQE) of a perovskite-based light-emitting diode (PELED) is a key indicator, comprising the internal quantum efficiency (IQE) and light extraction efficiency (LEE).
