摘要：

Highly-condensed thin films of Cu2FeSnS4 (CFTS) nanoparticles are prepared on FTO substrates by spin-coating CFTS precursor solution followed by a short thermal annealing at low temperature for the first time. The CFTS film has a band gap of 1.53 eV and an absorption coefficient higher than 104 cm(-1) in the wavelength range of 300-1100 nm. The thin film solar cells structured as FTO/CFTS/CdS/Al are fabricated and it is demonstrated that the optimized CFTS film thickness for such devices is around 125 nm. (C) 2017 Elsevier B.V.
