In this work we report the Na incorporation from Na-doped Mo (Mo-Na) back contact for kesterite Cu2ZnSnS4 solar cells on flexible stainless steel substrates. It is demonstrated that Na can be effectively incorporated into CZTS by inserting Mo-Na laye

Sulfide kesterite Cu2ZnSnS4 provides an attractive low-cost, environmentally benign and stable photovoltaic material, yet the record power conversion efficiency for such solar cells has been stagnant at around 9% for years. Severe non-radiative recom

Heterojunction interface of the Cu$_{\mathbf {2}}$ZnSnS$_{\mathbf {4}}$ (CZTS) solar cells is one the critical factors for performance loss, especially when applying Zn-based alternative buffer replacing CdS. In this work, the CZTS/ZnCdS interface qu
