Abstract

Inverted OPV devices based on sol-gel derived vanadium oxides (VOx ) as an interfacial layer are demonstrated. The VOx shows excellent characteristics as a hole-transporting and protecting layer. The constructed devices exhibit enhanced performance with the studied polymers and are highly durable under accelerated conditions for long time periods.
