摘要：

Cu2ZnSnS4 photovoltaic semiconductor films (CZTS) were deposited by RF magnetron sputtering using a home-made Cu2S-ZnS-SnS2-S mixed powder target. The phase information of the CZTS films was studied via X-ray diffraction and Raman scattering techniques. The films prepared at substrate temperatures between 150 degrees C and 200 degrees C exhibited strong preferential orientation of grains along < 112 >. Higher substrate temperature (over 200 degrees C) induced a flower-like structure of CZTS films without preferred orientation and the light absorption coefficients were largely enhanced. The energy band gaps of CZTS films deposited at different substrate temperatures were approximate 1.7 eV. (C) 2012 Elsevier B.V. All rights reserved.
