Highly accelerated lifetime testing in power electronics

Accelerated Lifetime Testing of OLED Luminaires

Lifetime Aspects of Wearable Electronics

In the course of two European projects the endurance behavior of stretchable electronic substrates and of electronic textiles was investigated. The results have to a large extent been published already. In this work new analyses to the earlier results are presented. Straightforward analytical approaches are used to describe fatigue under cyclic mechanical loading in the two technologies. For st...

Power Electronics and Wind Power

Renewable energy facilities will constitute a major contribution to electrical power in the future. The wind turbine will, together with biomass, form the major renewables parts up to year 2030 including erection of offshore wind farms. The wind is a non-storable energy source, whose electric energy needs priming into interchangeable energy to be competitive for large-scale power generation. An...

Crosslinked Remote-Doped Hole-Extracting Contacts Enhance Stability under Accelerated Lifetime Testing in Perovskite Solar Cells.

A crosslinked hole-extracting electrical contact is reported, which simultaneously improves the stability and lowers the hysteresis of perovskite solar cells. Polymerizable monomers and crosslinking processes are developed to obviate in situ degradation of the under lying perovskite. The crosslinked material is band-aligned with perovskite. The required free carrier density is induced by a high...
