Abstract Two‐dimensional (2D) transition metal dichalcogenides (TMDCs) have gained much attention due to their excellent electronic and optoelectronic properties. The reasonable band gap, higher light‐matter interaction, hundreds of categories as well wafer‐scale growth Si‐compatible fabrication etc. proof immense potential for next‐generation solar cells. Over the past years, a variety specific device structure are investigated including multi‐field tunable 2D TMDCs‐based photovoltaic cell since its is easily tunable. Their work function distributes in wide range which facilitate interfacial modulation optimize electron/hole transfer layer perovskite‐/organic‐based cell. In this review, recent developments TMDCs comprehensively described. First, energy diagram traditional semiconductor TDMCs discussed. Then, introduced considering homojunction, heterojunction Schottky‐junction tunability. Third, role photosensitive modifying silicon‐based cells, applications cells summarized or active layer. Lastly, prospect future materials, process trends practical presented.
