Solution-based approaches are regarded as one of great potential methods for preparing Cu2ZnSn(S,Se)4 thin film solar cells due to the advantages of simple operation, high material utilization, and low material cost. This review systematically summarized recent development on the solution-based approaches for preparing Cu2ZnSn(S,Se)4 thin film solar cells, i.e., spray pyrolysis, bath-based aqueous solution, nanoparticle solution and direct solution coating methods. Recent research results on solution-based high-efficient Cu2ZnSn(S,Se)4 thin film solar cells based on the optimization of cation ratio, sintering conditions and selenium conditions, as well as Na, Ge and other metal elements doping were represented. This review gave the advantages and problems in the process of solution-based preparation. t In addition, the future research could also focus on membrane composition and reaction pathway, as well as some effective methods to reduce the intrinsic defects of Cu2ZnSn(S,Se)4 absorber layer.
