Cu2FeSnS4 (CFTS) nanoparticles have been synthesized by solvothermal method and their structural and photovoltaic properties have been studied. The bandgaps of the as-synthesized particles are about 1.56 ~ 1.67 eV determined by UV-Vis absorption spectra. The average grain sizes of CFTS nanoparticles increase with increasing the reaction temperatures and times, while decrease with increasing the amounts of Ethylenediamine (En). CFTS nanosheets will form at longer reaction times and higher reaction temperatures. The photovoltaic properties have been investigated with CFTS nanoparticle-sensitized solar cells, and the power conversion efficiencies are found to increase with decreasing the average sizes of the nanoparticles..
