Fig. 1: Architecture and performance of transparent perovskite light-emitting diode.
From: Transparent near-infrared perovskite light-emitting diodes
a Device structure of ITO/AZO/PEIE/FAPbI3/Poly-TPD/MoO3/Al/ITO/Ag/ITO PeLED. b Electroluminescence spectra of PeLED from 1.6 to 4.0 V. Inset shows the near-infrared photo of a 120-mm2 PeLED. c Combined current density vs. voltage (black solid and dashed lines) and radiance vs. voltage plots (blue solid and dashed lines) of PeLED. d External quantum efficiency vs. current density plots of PeLED. Solid lines represent device measurements from the front and dashed lines represent measurements from the back.
