説明
<jats:sec><jats:label/><jats:p>A proof‐of‐concept tandem solar cell using Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> and Sb<jats:sub>2</jats:sub>Se<jats:sub>3</jats:sub> as top and bottom cell absorber materials is demonstrated. The bandgaps of Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> and Sb<jats:sub>2</jats:sub>Se<jats:sub>3</jats:sub> are 1.74 and 1.22 eV, perfectly satisfying the requirement of tandem solar cells. The application of few‐layer graphene enables high transmittance and excellent interfacial contact in the top subcell. By controlling the thickness of the top cell for maximizing the spectral application, the tandem device delivers a power conversion efficiency of 7.93%, which outperforms the individually optimized top cell (5.58%) and bottom cell (6.50%). Mechanistical investigation shows that the tandem device is able to make up voltage loss in the subcells, which is a critical concern in the current antimony chalcogenide solar cells. This study provides an alternative approach to enhancing the energy conversion efficiency of antimony selenosulfide.</jats:p></jats:sec>
