Abstract

Cu₂ZnSnS₄ (CZTS) is a promising material for thin film solar cell applications. On the other hand, spray pyrolysis technique has been identified as a low cost and versatile technique which could reduce cost per watt peak of panels. In this work, the sprayed-CZTS thin films are fabricated at substrate temperature in the range of 340–420 °C. The substrate temperature influence on the structural, morphological, electrical and optical properties is evaluated. It is found that CZTS thin films grown under 390 °C and thermally treated are the most appropriate for solar cell applications. CZTS thin films with Cu/(Zn + Sn) and Zn/Sn compositional ratios near to the optimal ones are achieved. Finally, resistivity, Hall mobility and carrier density values in the range of 0.5–80.2 Ω·cm, 0.6–10.3 cm²/Vs and 2.2 × 10¹⁷–7.0 × 10¹⁸ cm^{− 3}, respectively, are reported.
