Abstract
Cu2SnS3 (CTS), an environmentally friendly semiconductor material that has little impact on the human body, was developed as an alternative material to silicon-based solar cells, which are currently the mainstream product in the solar cell market. In this study, by adopting the sol-gel dip coating method, a CTS thin film was produced at low cost without using a vacuum process for use as a solar cell light absorption layer. CTS thin films were prepared while varying the annealing temperature and the amount of α-cyclodextrin added, and the results were compared by different evaluation methods. In addition, the samples to which α-cyclodextrin was added showed peaks due to CTS at (112) and (220) in all the samples. The crystallinity was not found to depend on the amount of α-cyclodextrin added.
