Fabrication of a demonstrator that shows improved stability compared to the reference stack

At the end of the action, a physical OLED demonstrator with lab scale dimensions (about 2 by 2 cm) will be presented to the public including device performance parameters. There are two reporting cases: 1) WPs 1-3 have identified stability problems in the reference device, these shortcomings could be suppressed by material design, composition, and/or device engineering approaches, such that the demonstrator shows improved lifetime compared to the reference device. 2) WPs 1-3 have identified stability problems in the reference device, but no concept to improved device stability could be realized in the action. Here, the demonstrator is the reference device with the addition of the identification of origins of device instabilities.
