title: Novel counter electrode catalysts of niobium oxides supersede Pt for dye-sensitized solar cells.
abstract: Synthesized niobium oxides (Nb(2)O(5) and NbO(2)) were applied for the first time as counter electrodes (CEs) in dye-sensitized solar cells (DSCs). The DSC using NbO(2) CE showed a higher power conversion efficiency of 7.88%, compared with that of the DSC using Pt CE (7.65%).
