Abstract
Al-doped zinc stannate (Zn2SnO4: Al or Zn-Sn-O: Al or AZTO) has attracted considerable attention as a next-generation transparent conducting oxide (TCO) owing to its properties. In this study, AZTO films were deposited by co-sputtering Al-doped zinc oxide (AZO) and SnO2 targets at room temperature. The as-deposited AZTO films were confirmed to be satisfactorily adherent with good uniformity. These films had an average transmittance of over 80%, energy band gap of >3.5 eV, and relatively low electrical resistivity of 1.29×101 Ω. cm. The composition ratio of Zn/Sn at 140 W of SnO2 power was approximately 2, indicating the formation of AZTO film with stoichiometric composition of Zn2SnO4: Al at this power. Further, the Cu(InGa)Se2 (CIGS) device fabricated with AZTO (140 W) as a TCO exhibited an efficiency of 0.73%, with a VOC of 0.51 V, J}SC of 3.76 mA/cm2, and FF of 38.4%. Furthermore, the conversion efficiency of CIGS cell was enhanced to 2.82% by employing the AZTO film deposited at the elevated temperature of 350oC.
