Degradation occurs via a combination of three primary pathways: (1) cathodic oxidation, (2) active layer phase segregation, and (3) anodic diffusion. Fully degraded devices were subjected to thermal annealing under inert atmosphere. Degraded solar cells possessing Ca/Ag electrodes were observed to regenerate their performance, whereas solar cells having Ca/Al electrodes exhibited no significant regeneration of device characteristics after thermal annealing. Moreover, the solar cells with a P3HT:ICBA active layer exhibited enhanced regeneration compared to P3HT:PCBM active layer devices as a result of reduced changes to the active layer morphology. Devices combining a Ca/Ag cathode and P3HT:ICBA active layer demonstrated ∼50% performance restoration over several degradation/regeneration cycles.]]> Wed 11 Apr 2018 10:49:00 AEST ]]> Scanning transmission x-ray microscopy of polymer nanoparticles: probing morphology on sub-10nm length scales https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17883 Sat 24 Mar 2018 07:56:19 AEDT ]]>
