In this study, a model of steady state and time-dependent exciton diffusion, including singlet and triplet excitons, is developed. It is coupled with a modified Poisson and drift-diffusion solver to explain the mechanism of hyper triplet-triplet fusion (TTF) organic light-emitting diodes (OLEDs). Various characteristics of OLEDs are demonstrated using this modified simulator, and it can also be used to explain the mechanism of hyper-TTF-OLEDs and analyze the loss from different exciton mechanisms. Furthermore, optimizations of hyper-TTF-OLEDs are performed, increasing the internal quantum efficiency by approximately 33%.
In this study, a steady state and time-dependent exciton diffusion model including singlet and triplet excitons coupled with a modified Poisson and drift-diffusion solver to explain the mechanism of hyper triplet-triplet fusion (TTF) organic light-emitting diodes (OLEDs) is developed. Using this modified simulator, various characteristics of OLEDs, including the current-voltage curve, internal quantum efficiency, transient spectrum, and electric profile are demonstrated. This solver can also be used to explain the mechanism of hyper-TTF-OLEDs and analyze the loss from different exciton mechanisms. Furthermore, we perform additional optimization of hyper-TTF-OLEDs that increases the internal quantum efficiency by approximate to 33% (from 29% to 40%).
