Congratulations Dr. Klaus
Congratulations to Klaus for finishing his PhD studies with distinction. Klaus worked for 5 years on building accelerated setups for lifetime measurements on solar cells, and, demonstrated most impressively the value of these setups by ageing organic solar cells under 300 suns and more. The development of a most intelligent temperature sensor was the breakthrough for his work, and, for the first time in highly accelerated lifetime measurements, Klaus could demonstrate that it is possible to decouple temperature stress from light stress.
We will keep his setups “Death Star”, “Galactica” and “Enterprise” in best memories and maintain them in best conditions!
