A simple, solution‐processed route to the development of MoO x thin‐films using oxomolybdate precursors is presented. The chemical, structural, and electronic properties of these species are characterized in detail, within solution and thin‐films, using electrospray ionization mass spectrometry, grazing angle Fourier transform infrared spectroscopy, thermogravimetric analysis, atomic force microscopy, X‐ray photoelectron spectroscopy, and ultraviolet photoelectron spectroscopy. These analyses show that under suitable deposition conditions the resulting solution processed MoO x thin‐films possess the appropriate morphological and electronic properties to be suitable for use in organic electronics. This is exemplified through the fabrication of poly(3‐hexylthiophene):[6,6]‐phenyl C 61 butyric acid methyl ester (P3HT:PC 61 BM) bulk heterojunction (BHJ) solar cells and comparisons to the traditionally used poly(3,4‐ethyldioxythiophene)/poly(styrenesulfonate) anode modifying layer.
