The serious driving voltage rise in HOD could be evidence of EPQ causing device degradation. Strong deterioration was observed when the recombination-zone coincides with the interface-mixing zone, where a higher degree of EPQ occurs. Device lifetime was improved by 8 times as the recombination was confined away from interface mixing zone of solution-processed device.
