Perovskite-based Light Emitting Diodes (PeLEDs) are the fastest-growing new generation of cost-effective and efficient multicolor LEDs. This work shows different deposition techniques involved in the manufacturing of PeLEDs and the making of a fully functional device. Individual layers have been characterized morphologically by optical microscopy and scanning electron microscopy (SEM) and optical properties have been measured by UV-Vis spectroscopy and PL spectra.
Complete device performance has been analyzed by comparing its I-V curves. Short-term stability analysis has been carried out by monitoring current and electroluminescence (EL) at constant voltage over time. Treating the devices under controlled humidity conditions seems to improve PeLED performance. Results notify that post treatment might be a necessary step in elevating device efficiencies
