摘要：

Cu2ZnSnS4 (CZTS) thin films were grown onto glass substrates using pneumatic spray pyrolysis method under different growth conditions. The electrical properties have been investigated by means of dark and illuminated conductivity measurements in the 293-353 K temperature range and Hall measurements at room temperature. The influence of growth parameters on the grain boundary barrier height and other associated grain boundary parameters of the CZTS thin films was determined from electrical, optical, and morphological characterization. The CZTS electrical properties relation with secondary phases formation as well as with transport mechanisms is presented. Finally, CZTS electrical parameters impact on the properties of polycrystalline thin film solar cells is discussed. (C) 2014 Elsevier B.V. All rights reserved.
