- •
We study the charge balance limitations in simplified PHOLEDs.
- •
Simplified PHOLEDs are hole-rich and electron leakage also contributes to charge imbalance.
- •
Using electron blocking HTL can increase device efficiency by as much as 25%.
- •
Changing layer thickness does not impact charge balance in devices using high mobility transport materials.
- •
Using charge traps in a thin layer within the transport layers can be effective for studying charge balance.
