Resumen

Low cost single stoichiometric target sputtering of Cu2ZnSnS4 (CZTS) precursor has been adopted to fabricate CZTS solar cells. The effect of a series of deposition pressures and deposition durations on the device performance has been investigated. A 3.74% efficient solar cell has been achieved at a base pressure of 1 × 10-4 Torr with a stoichiometric target, which to the authors? knowledge, is the record efficiency for such a stoichiometric target.
