Organic photovoltaic (OPV) solar cells show great promise but suffer from short operating lifetimes. This study examines the role that the selection of materials for the hole extraction interface in inverted OPV devices plays in determining the lifetime of a device. In the first part of the study, the effects of thermal degradation were examined. It was found that devices containing MoO3 HTLs and silver top electrodes exhibit an open-circuit voltage (VOC)/fill factor (FF)-driven mechanism. Physical characterisation experiments showed that, with heating, the silver electrode undergoes de-wetting. With thin electrodes this can result in the catastrophic failure of the device. A fracture analysis study found that silver-containing devices expe...
