Quaternary compounds Cu 2 FeSnS 4 (CFTS), a promising alternative material for solar cell absorber layer, were successfully synthesised by a liquid reflux method in a mixture solvent of triethylenetetramine‐ethylene glycol (TETA‐EG, 1:1, v/v) at 230°C for 3 h under the atmospheric pressure condition. The phase, micro‐structure, morphology, chemical composition and optical properties of the as‐synthesised CFTS micro/nano particles were characterised using X‐ray diffraction, scanning electron microscopy, energy dispersive X‐ray spectrometry and ultraviolet‐visible absorption spectrophotometer. The results showed that the stannite structured CFTS micro/nano particles with close to theoretical stoichiometric ratio were pure and well‐crystallised, the particle size ranged from 70 to 240 nm and the particles were well‐distributed, the band gap was about 1.25 eV which indicated its suitable application as the absorption layer of thin film solar cells.
