In this study, 2‐D layer structured Ti3C2 is synthesized using etching method under lower temperature, and then it is applied in dye‐sensitized and perovskite solar cells as counter electrode with higher activity compared with conventional TiC particles counter electrode. The dye‐sensitized solar cells fabricated using 2‐D layer structured Ti3C2 counter electrode achieves a power conversion efficiency of 9.57%, much higher than that of the counterpart device fabricated using TiC particles counter electrode (7.37%). The excellent activity of Ti3C2 electrode can be attributed to the superior charge transfer and mass transport properties owing to the specific 2‐D layer structure. Moreover, the fabricated 2‐D layer structured Ti3C2 is attempted to be applied in perovskite solar cells, thereby achieving a power conversion efficiency of 7.78% without further optimization. Thus, it exhibits a potential candidate to the noble metal electrodes.
