This review highlights the recent advances in utilizing a combinatorial strategy of mechanistic investigation, theoretical prediction and experimental validation to develop cheap and earth-abundant high-performance electrocatalysts as counter electrode materials for dye-sensitized solar cells. The effectiveness of the combinatorial strategy over the conventional ‘trial-and-error’ tactic is illustrated with plentiful successful examples of earth-abundant materials. Perspectives are given to elucidate the opportunities and challenges.
