P-I-N Structure and Emission Zone in Laminated LEC

08.09,20220

Brief Introduction

This video demonstrates how to make a photoelectrochemical cell into a single emitting organic layer sandwiched between two electrodes, thereby achieving cost-effective lighting applications. Ideal devices are usually considered as p-i-n structures with doped regions on the electrodes, which facilitate the balance of hole and electron injection. Here, we first introduce a method based on spectral photocurrent response measurement combined with optical modeling to determine the center of the intrinsic region in interlayer LECs. Combined with capacitance measurement, generate detailed images of the evolution of p-i-n structure. Secondly, the angle dependent emission spectrum emission region is determined through simulation experiments.

Phelos OLED Spectral Measurement System/Angular Spectral Analyzer

Phelos is used to measure the emission spectral characteristics and polarization angles of OLEDs, perovskite LEDs, and other light-emitting devices. It can also measure the s and p polarization spectra of the devices, the relationship between emission spectra and angles, and calculate the emission angle and position distribution of excitons in the emitting layer.
