采用快速喷雾热解法制备了银（Ag）掺杂的kesterite Cu2ZnSnS4 （CZTS）薄膜。晶体学分析表明成功。将不同数量的银（Ag /(Ag + Cu)）以约0.1的比例均匀地掺入CZTS的晶格中，而不形成其他杂质化合物。从形态学研究的结果来看，Agincorporated薄膜比CZTS薄膜具有更大的晶粒。样品中Ag含量相对较低（Ag/ Ag + CO）。0.02)，形态致密，无明显空隙和针孔。然而，在CZTS薄膜中Ag含量增加
A silver (Ag)-incorporated kesterite Cu2ZnSnS4 (CZTS) thin film was fabricated by a facile spray pyrolysis method. Crystallographic analyses indicated successful. incorporation,of various-amounts of Ag up to a Ag/(Ag + Cu) ratio of ca. 0.1 into the crystal lattice of CZTS in a homogeneous manner without formation of other impurity compounds. From the = results-,of morphological investigations,, Agincorporated films- had larger crystal grains than the CZTS film. The sample with a relatively low Ag content (Ag/(Ag + CO of ca:. 0.02) had a:= compact morphology Without: appreciable voids and pinholes. However, an increase In the Ag content in the CZTS film
