采用喷雾热解法制备了Cu 2 ZnSnS 4薄膜。以一水乙酸铜、二水乙酸锌、二水氯化锡、三水合钠和纯硫磺粉为原料，分别以N，N-二甲基甲酰胺和单乙醇胺为溶剂和稳定剂制备喷雾热解法。将该溶液涂覆在Mo涂覆的钠钙玻璃基底上，并且在涂覆溶液之后，将膜在N2气体气氛中在360、440和520 °C下退火，将两个膜面对面放置或不放置。发现面对面退火过程防止了退火过程中S和Sn的损失，并且在440和520 °C下面对面放置的另一种前体退火的样品在表面图像中显示出窄且大的X射线衍射峰和大晶粒。
Cu2ZnSnS4 thin films were deposited by the spray pyrolysis method. Copper(II) acetate monohydrate, zinc(II) acetate dihydrate, tin(II) chloride dihydrate, sodium trihydrate, and pure sulfur powder were used as the starting materials of spray pyrolysis solutions, and N,N-dimethylformamide and monoethanolamine were used as the solvent and the stabilizer, respectively. The solution was coated on a Mo-coated soda lime glass substrate and after coating solutions, the films were annealed in a N2 gas atmosphere at 360, 440, and 520 °C with or without placing two films face-to-face. It was found that the face-to-face annealing process prevented losses of S and Sn during the annealing process and the samples annealed with another precursor placed face-to-face at 440 and 520 °C showed narrow and large X-ray diffraction peaks and large grains in the surface images.
