Hole-induced degradation in the presence of excited states is found to be a major culprit for the fast degradation in solution-processed devices. Degradation in the solution-processed emitting layer (EML) is found to be strongly dependent on the initial hole injection/transport properties of the EML. Gas chromatography-mass spectrometry (GC-MS) studies on solvents used to prepare the solution-processed EMLs reveal that solvent impurities are the dominant reason for their substantially shorter operational lifetime compared with thermal evaporated devices.}, number={37}, journal={JOURNAL OF MATERIALS CHEMISTRY C}, author={Liu, Shuyi and Peng, Cheng and Cruz, Alexandria and Chen, Ying and So, Franky}, year={2016}, month={Oct}, pages={8696–8703} }
