Abstract
Short‐term (up to ∼2 hr) stabilization of photoanodes in aqueous electrolytes has been accomplished by coating them with polymer films comprising polystyrene with pendant complexes (bpy = 2,2′‐bipyridyl). The electrolytes contained the , , , , and (EDTA = ethylenediamine‐tetraacetic acid) redox couples. The best photoelectrochemical response was observed in the presence of the redox couple and an AM 1 optical‐to‐electrical conversion efficiency of ∼12% was reached in nonoptimized systems. The possible role of the Ru complex in the mode of charge transport across the polymer‐coated interface is finally discussed.Keywords
