Abstract

This study presents a novel approach to the synthesis of highly crystalline Cu2SnSe3 nanoink from elemental sources using a solution-based method with isophorondiamine chelation. The synthesized Cu 2SnSe3 nanoparticles are 10-20 nm in size with an atomic ratio of approximately 2:1:3. Characterization of X-ray diffraction confirms that as-synthesized Cu2SnSe3 nanoparticles have a single-phase cubic structure that enables their stable suspension in an ink solution. Hall-effect analysis of thin films obtained via ink printing and annealing show p-type conduction and UV-vis data demonstrates an optical bandgap of 0.91 eV. The proposed synthesis process may be suitable for printable photovoltaic applications as a low-cost process for the fabrication of solar cells. Crown
