Abstract Photoelectrochemical (PEC) cells are regarded as a promising approach to convert sunlight chemical fuels, whereas the serious photo‐induced charge recombination of semiconductor photoelectrode hinders its solar conversion efficiency. Over past few decades, designing and constructing heterojunction photoelectrodes via thermodynamically favorable transfer have been proven be effective in boosting separation. However, conventional construction strategy generally introduces incompatible, nonconformal, or defective interfaces, leaving considerable room improve efficiency photoelectrodes. To compensate for unsatisfied efficiency, some novel strategies, such grain boundary engineering, band gap field‐effected etc., adopted provide additional driving force, which significantly improves In this review, these strategies discussed beyond construction, prospects development applications photoanodes also proposed.
