摘要：

This work presents the results of a comprehensive study of the structural characteristics and chemical composition of Cu2ZnSnS4 (CZTS) nanocrystals and thin films. Appropriate layers were deposited onto the flexible polyimide substrates by spraying a suspension of nanocrystals followed by low-temperature annealing at 200 degrees C for (10-120) min in Ar atm. The study of the samples by XRD and Raman spectroscopy showed that nanocrystals and CZTS thin films contain the kesterite phase with small impurities of CuxSnySz, CuxS. Established that the chemical composition of the obtained films corresponds to the composition of the nanocrystals used for its application in solar cell development. Increasing the growth time of nanocrystals and annealing time of films causes an improvement in the crystalline quality of the main phase of the samples - kesterite. Showed that the CZTS thin films obtained by the presented method can be used as absorbers in third-generation solar cells.
