TY - JOUR T1 - Preparation and evaluation of Cu2ZnSnS4 thin films by sulfurization of E-B evaporated precursors JF - Solar Energy Materials and Solar Cells Y1 - 1997 A1 - Hironori Katagiri A1 - Nobuyuki Sasaguchi A1 - Shima Hando A1 - Suguro Hoshino A1 - Jiro Ohashi A1 - Takaharu Yokota KW - EB evaporated precursors AB - By sulfurization of EB evaporated precursors, CZTS(Cu2ZnSnS4) films could be prepared successfully. This semiconductor does not consist of any rare-metal such as In. The X-ray diffraction pattern of CZTS thin films showed that these films had a stannite structure. This study estimated the optical band gap energy as 1.45 eV. The optical absorption coefficient was in the order of 104cm−1. The resistivity was in the the order of 104 Ω cm and the conduction type was p-type. Fabricated solar cells, Al/ZnO/CdS/CZTS/Mo/Soda Lime Glass, showed an open-circuit voltage up to 400 mV.
