Research on the High-Temperature Lifetime Stability of Tandem Devices

Late-News

Description:

We found that the CGL of our tandem devices is not stable enough. n-dopant and p-dopant may react at the interface of n-CGL and p-CGL, which will cause lifetime suddenly drops accompanied by a rapid increase in voltage under ultra-high temperature conditions. Therefore, we have developed a new CGL structure which makes our tandem OLED can operate stably at 110°C with a very small V-shift voltage.
