Degradation Analysis of Organic Charge-Generation Layer by Impedance Spectroscopy

Distinguished

Description:

Understanding the degradation mechanism of the charge generation layer (CGL) is crucial for the development of stable tandem organic light-emitting diodes (OLEDs). In this study, we utilized capacitance-voltage measurements, modulus Cole-Cole and Bode plots, and equivalent circuit fittings to investigate the degradation mechanism. The results show that the diffusion of dopants is responsible for the electrical degradation of CGL.
