Summary

This summary is machine-generated.

Photon upconversion in perovskite/rubrene systems is better understood by examining the interface. Noncovalent interactions and band bending explain initial efficiency and subsequent steady-state upconversion.

Background:

Perovskite-sensitized photon upconversion (PS-UC) via triplet-triplet annihilation (TTA) in rubrene is a promising technology.
Unanswered questions remain regarding the interfacial mechanisms and processes governing PS-UC efficiency.

Purpose of the Study:

To investigate the perovskite/rubrene interface in detail.
To elucidate the underlying mechanism of photon upconversion and observed phenomena like reversible photobleaching.

Main Methods:

Detailed investigation of the perovskite/rubrene interface.
Analysis of noncovalent interactions and band bending effects.
Study of charge transfer dynamics upon illumination.

Main Results:

Noncovalent interactions between perovskite and rubrene passivate surface traps.
Band bending creates a space charge region, precharging rubrene with holes.
Initial illumination facilitates rapid electron transfer and efficient TTA upconversion.

Conclusions:

The perovskite/rubrene interface plays a critical role in TTA upconversion efficiency.
Surface trap passivation and hole precharging are key to initial high efficiency.
A dynamic equilibrium explains the transition to steady-state upconversion efficiency.
