Is it necessary to add MoO3 on top of TFB (HTL) in order to measure red PeLEDs such as CsPbI3 and FAPbI3?

During the fabrication of CsPbI3 LEDs with ZnO as ETL and TFB as HTL, I deposited Au on top of the TFB layer. However, upon measuring the devices, there was no photoresponse observed. Is it plausible that the incorporation of MoO3 between the TFB and Au layers is necessary?

Chuck A Arize

Yes, it's common to add MoO3 on top of TFB (HTL) to measure red PeLEDs like CsPbI3 and FAPbI3, as it improves device performance and stability.
