We report on the latest progress on oligomer based vacuum deposited tandem and multi-junction solar cells. Efficiencies above 13% together with excellent durability are now routinely achieved for lab scale multi-junction cells. The world’s first fully integrated roll-to-roll-production tool for organic tandem junction solar cells on PET substrate film has been successfully ramped-up and delivers high quality solar films with efficiencies above 7% on the active area.

We will also discuss both the intrinsic and the extrinsic lifetimes of glass and flexible modules and identify key factors necessary to insure high lifetimes. Additionally, we will show a number of demonstration objects successfully installed by Heliatek and its partners as well as their observed lifetime and yield under real outdoor conditions and their dependence on different factors such as temperature and illumination.

As a next step, reduction of device complexity suggests the use of integrated front sheets. To do so, we will combine ultrabarrier films with transparent electrode function. The EU project ALABO develops the required technologies, especially regarding laser structuring of OPV on barrier foils. We will report latest progress in this field.
