The first scientific meeting of MOSTOPHOS took place at Eindhoven on December 14th 2015, in occasion of the 6th month meeting of the project. The meeting has seen a lively discussion about all the modelling aspects of industrially-relevant OLED stacks and related progresses made by all groups. IAPP has started to grow the OLED stacks with materials provided by industrial suppliers reaching very good performances. Most of the other achievments reached so far are still confidential or under publication and will be communicated in the future.
