In article number 1900180 , Xiaosheng Fang, Husam N. Alshareef, Jr‐Hau He and co‐workers demonstrate a delaminated multi‐layer Ti 3 C 2 T x MXene contacted Si solar cell with a maximum power conversion efficiency (PCE) of ≈11.5%. The formation of an Ohmic junction of the metallic MXene to the n + ‐Si surface efficiently extracts the photogenerated electrons from n + np + ‐Si, decreases the contact resistance, and suppresses the charge carrier recombination, giving rise to the excellent open‐circuit voltage and short‐circuit current density. The work demonstrated here can be extended to other MXene materials as potential electrodes for developing high performing solar cells.
