A novel solution‐based approach is presented to process earth ‐ abundant Cu 2 ZnSn(S,Se) 4 absorbers using fully dissolved CZTS precursors in which each of the elemental constituents intermix on a molecular scale. This method enables the low‐temperature processing of chemically clean kesterite films with excellent homogeneity. The high performance of resulting optoelectronic devices represents a chance to extend the impact of CZTS into the next chapter of thin‐film solar cells.
