제목 | Synthesis of earth abundant Cu2SnS3 nanocrystals based thin film for solar cell application |
초록 | Cu2SnS3 (CTS) is one of the promising copper based photovoltaic materials because of its low cost, high optical absorption coefficient and non-toxicity. It has particular interest due to its band gap comparable with the CZTS and CIGS chalcogenide materials. In the present study, we report the fabrication of CTS nanocrystals (NCs) based thin film for the efficient solar cell. CTS NCs were synthesized by hot injection approach. A binder-free ink formulation method without a ligand exchange has been developed to fabricate high quality thin films. As synthesized thin film was allowed to anneal in a RTA, which shows the enhanced grain growth in S powder atmosphere. The structural, morphological and optical properties have been studied using X-ray diffraction, Raman spectroscopy, field emission scanning electron microscope, and UV- visible spectrometer. |
