Cu2SnS3 (CTS) thin films were synthesized onto a soda lime glass substrate coated molybdenum by sulfurization the Cu–Sn stacks were prepared using RF sputtering. The influence of Na-doped CTS, Sb-doped CTS, and Sb+Na co-doped CTS films on their physical properties has been investigated. The undoped and doped films have been illustrated in a monoclinic structure with no shifts in peak position. Larger grain size has been obtained with Sb doping compared to undoped CTS. Enhancement in photoluminescence sharpening and yield spectra were indicated in the existence of Na and/or Sb. The power conversion efficiency was enhanced by the addition of Na and/or Sb to the CTS absorber layer, from 0.32% for undoped CTS to 1.54, 1.89 and 0.76% for Na, Sb, and co-doping CTS, respectively. As a result, the influence of doping has improved all cell efficiency with an increasing ratio of 381, 490, 137% with Na, Sb, and co-doping, respectively.

“…From Raman analysis, it was confirmed that the crystal structure of CTS-1 and CTS-2 samples were monoclinic, and secondary phases were generated during the formation of the CTS absorber. Secondary phase reactions that occurred during CTS synthesis are in the following Equation ( 1) and (2) [9,38] :…”

“…[3,8] Low-cost, non-toxic, chemically stable, and made from earth-abundant elements make CTS absorber a suitable candidate for TFSCs. [9,10] In recent times, the CTS absorber has been studied extensively by various research groups for optoelectronic device applications. [11][12][13] Moreover, CTS absorber material can also be utilized for flexible substrates instead of traditional soda-lime glass (SLG), allowing a more advantageous roll-to-roll fabrication process, improving productivity, and reducing manufacturing costs compared to the conventional in-line process.…”

Cu2SnS3 (CTS) has various crystal structures and a wide bandgap energy range of 0.93–1.77 eV, depending on the crystal structure. The optical properties of CTS are very similar to those of Cu2ZnSnS4 (CZTS)‐based materials, as reported extensively in the past and is therefore in the spotlight as an absorber material. However, CTS thin film solar cells (TFSCs) are mainly studied on non‐flexible substrates, and little research has been focused on flexible substrates. When a flexible substrate is applied to CTS TFSCs, Zn is omitted from CZTS‐based materials, reducing raw material costs and enabling a roll‐to‐roll fabrication process; hence, the economic benefit is doubled. When CTS TFSCs are fabricated on a Mo foil substrate, voids exist at the back interface and the device characteristics markedly deteriorate. To solve this problem, the thickness of the CTS absorber layer is increased in this study by doubling the thickness of the precursor. As a result, Cu, Sn, and S display a more uniform distribution in the absorber layer, which further improves the light‐absorbing characteristics of CTS TFSCs. Finally, a device with a power conversion efficiency of 1.31% is obtained.
