The electronic and optical properties of Janus Ga2SeTe monolayer are calculated using first‐principles calculations and it is found that it has potential in solar cells. It is found that ultrathin cross‐plane pn‐junctions are obtained by stacking Ga2SeTe structures. The graphene‐Ga2SeTe‐graphene sandwich‐structured solar cells are configured to explore the device performance of Ga2SeTe solar cells. The photocurrent and the power conversion efficiency of the Janus Ga2SeTe solar cells are evaluated. The results show that multilayer Janus Ga2SeTe solar cells give rise to a photocurrent exceeding that of thin‐film silicon devices, indicating that Ga2SeTe is a potential material that could be used in photovoltaics devices.
