摘要: In this paper, novel hierarchical Cu2ZnSnS4 (CZTS) particles were synthesized by a solvothermal method. The effects of synthetic conditions, such as reaction temperature, time, solution concentration, and the amount PVP, investigated. results showed that size morphology CZTS can be controlled changing conditions PVP played an important role in formation final particles. Time-dependent nucleation growth governed nucleation–dissolution–recrystallization mechanism. optical electrical properties also Compared with spherelike nanocrystals, absorption typical decayed more slowly, indicating higher coefficient visible region. Meanwhile, current–voltage characteristics films indicated flowerlike fa...
