摘要：

Screen printing is a useful and simple method for coating layers of several solar materials, but care must be taken in preparing stoichiometric CZTS film due to its instability at a high processing temperature and a small chemical potential domain. This paper reports screen printing prepared CZTS films and the influence of sintering temperature on CZTS properties. The thermostability, structural, electronic and optical properties are studied. The direct optical band gap energies of the films vary from 1.39 to 1.60 eV, while the resistivities change from 830 to 6 Omega cm after sintering at different temperatures up to 550 degrees C. A high photosensitivity of 14% is achieved for the sample sintered at 450 degrees C. The phenomena observed are also discussed. (c) 2012 Elsevier B.V. All rights reserved.
