KZT型CZTS（Cu_2ZnSnS_4）是一种新兴的用于薄膜太阳能电池的吸收材料。在这里，我们报告了一种简单方便的路线，通过使用球磨金属前体合成CZTS薄膜;通过使用丙二醇作为粘合剂，尽管使用了太多的化学品，这可能会导致难以去除和减少不希望的有机碳层的机会形成的糊剂制备。这是一条快速、简单的制备具有良好性能的锌黄锡矿型CZTS薄膜的合成路线。利用透射电子显微镜（TEM）、X射线衍射仪（XRD）、扫描电子显微镜（SEM）、拉曼光谱仪、能量色散X射线分析仪（EDAX）和紫外-可见-近红外光谱仪对样品进行了表征。通过对金属前驱体进行球磨处理，得到了结晶度很低的纳米颗粒，粉末样品的TEM选区电子衍射（SAED）图谱显示了这一点。利用Doctor's Blade方法制备了CZTS薄膜。
Kesterite-type CZTS (Cu2ZnSnS4) is an emerging absorber material to be used in thin film solar cells. Here, we report a simple and convenient route to synthesize CZTS thin film by using ball milled metallic precursors; paste preparation by using propylene glycol as binder despite of using too many chemicals which may lead to make it difficult to remove and reduce the chance formation of undesired organic carbon layer. This is a fast and uncomplicated synthesis route for preparing kesterite type CZTS film with promising properties. Samples were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman, EDAX (Energy Dispersive X-ray Analysis) and UV-VIS-NIR spectrometer at different stages of work. Ball milling the metallic precursors, formed nano particles with little amount of crystallinity which was revealed from SAED (selected area electron diffraction) pattern of TEM of powder sample. We have fabricated CZTS thin film by Doctor's Blade m...
