Ta‐based compounds show Pt‐like behavior: Binary tantalum compounds as counter electrodes (CEs) in dye‐sensitized solar cells (DSCs) demonstrate Pt‐like electrocatalytic activity and competitive photovoltaic performance, matching the performance of DSCs with Pt CEs. The first‐principle density functional theory (DFT) calculations provide a strategy for understanding the relationship between the electronic structure and the catalytic activity of CE catalysts in DSCs.
