Effect of Interlayer on Doped Organic p–n Heterojunction Charge Generation Layers Using Impedance Spectroscopy (Adv. Electron. Mater. 7/2025)

Abstract

Charge Generation Layers

This cover image illustrates the operation mechanisms of an organic p–n heterojunction charge generation layer (CGL) with an interlayer under pristine and aged conditions through impedance spectroscopy and equivalent circuit investigations. The stability and efficient operation in CGLs, particularly focusing on charge injection and accumulation dynamics between the organic layers, highlight the role of the interlayer in optimizing performance.
