摘要

通过喷雾热解法合成了Kesterite Cu2ZnSnS4薄膜,随后在425至525°C的温度范围内退火。为了了解Ag对Cu2ZnSnS4结构性能的影响,通过电子显微分析、X射线相和拉曼分析、扫描探针显微镜和扫描电子显微镜研究了元素和相组成以及微观结构的变化。所获得的样品具有致密的形态,没有明显的空隙和孔隙,并且结晶为方沸石CZTS的四方结构。相分析表明,Ag以不同浓度掺入,没有形成其他杂质化合物。退火温度的增加导致相干散射区域的增加,而金属与硫族元素的化学计量比接近1,保持接近于Ag合金化时的化学计量比率。

Structure of Ag-Containing Cu2ZnSnS4 Thin Films, Obtained by Spray Pyrolysis

Structure of Ag-Containing Cu2ZnSnS4 Thin Films, Obtained by Spray Pyrolysis

Kesterite Cu2ZnSnS4 thin films were synthesized by the spray pyrolysis method with subsequent annealing at temperatures in the range from 425 to 525°C. To understand the impact of Ag on the Cu2ZnSnS4 structural properties, changes in the elemental and phase composition, as well as microstructure were studied by electron microanalysis, X-ray phase and Raman analysis, scanning probe microscopy and scanning electron microscopy. The obtained samples have a compact morphology without appreciable voids and pores and crystallize in the tetragonal structure of kesterite CZTS. Phase analysis indicated incorporation of Ag in different concentrations without formation of other impurity compounds. An increase in the annealing temperature leads to an increase in the coherent scattering region, while the stoichiometric ratio of metals to chalcogen approaches 1, remaining close to that upon Ag alloying.
