Quaternary Cu2ZnSnS4 (CZTS), a P-type semiconducting material with a direct band gap of 1.4 to 1.5eV and high absorption coefficient (104 cm-1) in the visible range has been considered as an alternative absorber layer in the fabrication of solar cells owing to its earth abundant and environmentally benign constituents. In this paper, we report the study of CZTS nanoparticles synthesized by solvothermal...
