主　　题：Solution processable Annealing free Molybdenum oxide Organic solar cell 

摘      要：Molybdenum oxide(MoO_(x))is a commonly used hole extraction material in organic *** MoO_(x) interlayer is deposited typically via thermal evaporation in *** meet the need for rollto-roll manufacturing,solution processing of MoO_(x) without post-annealing treatment is ***,we demonstrate an effective approach to produce annealing-free,alcohol-processable MoO_(x) anode interlayers,namely S-MoO_(x),by utilizing the bis(catecholato)diboron(B_(2) Cat_(2))molecule to modify the surface oxygen sites in MoO_(x).The formation of surface diboron-oxygen complex enables the alcohol solubility of S-MoO_(x).An enhanced light utilization is realized in the S-MoO_(x)-based organic *** affords a superior short-circuit current density(Jsc)close to 26 mA cm^(-2) and ultimately a high power-conversion efficiency(PCE)of 15.2%in the representative PM6:Y6 based inverted OPVs,which is one of the highest values in the inverted OPVs using an as-cast S-MoO_(x) anode interlayer.
