This bilayered heterostructure has not been studied to date in the literature theoretically or experimentally and we have demonstrated its potential application as a Schottky barrier solar cell. Our study predicts that the ZrSe 2 (1T)@ZrTe 2 (1T) bilayered heterostructure is a suitable material for an ultrathin Schottky barrier solar cell.

Surface analyses combined with barrier‐height studies indicate that Cu2O Schottky barriers made with low‐work‐function metals (Yb, Mg, and Mn) are essentially Cu/Cu2O cells due to reduction of the Cu2O surface and subsequent interdiffusion phenomena. The copper‐rich region essentially determines the barrier height. As a result, efficiencies of Cu2O Schottky‐barrier solar cells are ...
