Abstract ：
The effect of the deposition temperature of the buffer layer In2S3 on the band alignment of CZTS/In2S3 heterostructures and the solar cell performance have been investigated. The In2S3 films are prepared by thermal evaporation method at temperatures of 30, 100, 150, and 200 degrees C, respectively. By using x- ray photoelectron spectroscopy ( XPS), the valence band offsets ( VBO) are determined to be 0.28 +/- 0.1, 0.28 +/- 0.1, 0.34 +/- 0.1, and 0.42 +/- 0.1 eV for the CZTS/In2S3 heterostructures deposited at 30, 100, 150, and 200 ffi C, respectively, and the corresponding conduction band offsets ( CBO) are found to be 0.3 +/- 0.1, 0.41 +/- 0.1, 0.22 +/- 0.1, and 0.01 +/- 0.1 eV, respectively. The XPS study also reveals that interdiffusion of In and Cu occurs at the interface of the heterostructures, which is especially serious at 200 degrees C leading to large amount of interface defects or the formation of CuInS2 phase at the interface. The CZTS solar cell with the buffer layer In2S3 deposited at 150 degrees C shows the best performance due to the proper CBO value at the heterostructure interface and the improved crystal quality of In2S3 film induced by the appropriate deposition temperature. The device prepared at 100 degrees C presents the poorest performance owing to too high a value of CBO. It is demonstrated that the deposition temperature is a crucial parameter to control the quality of the solar cells.

Abstract ：
By a simple and economical sol-gel and spin-coating technique, fine quality Cu2ZnSnS4 (CZTS) thin films were formed on flexible molybdenum foils. The CZTS thin films annealed at 500 degrees C possessed good compositional, morphological, structural, optical and electrical properties for solar cells. The best flexible solar cell with a structure of Mo foil/CZTS/CdS/ZnO/AZO/A1 exhibited a power conversion efficiency of 2.25%, with short circuit current density of 13.52 mA/cm(2), open circuit voltage of 370 mV and fill factor of 0.45. Meanwhile, the PV performances of the flexible CZTS-based solar cell on molybdenum foil were investigated in detail. (C) 2017 Elsevier B.V. All rights reserved.

Abstract ：
Zinc sulfide (ZnS) buffer layer is one of the most promising potential candidates for solar applications due to its no toxicity, wider energy bandgap compared with cadmium sulfide (CdS) buffer layers. The ZnS thin films doped with 0-4 at% In have been grown by a Chemical Bath Deposition (CBD) method. The X-ray diffraction analysis indicates that all the films show an obvious peak corresponding to (111) plane of cubic form ZnS. All the ZnS: In films have a high transmittance of about 85% in the visible region with a high energy bandgap of about 3.60 eV. The electrical resistivity of the In-doped samples is decreased from 10(6) Omega cm (undoped sample) to 104 Omega.m after doping with 0.5 at% In. The detailed analysis about the change of bandgap, resistivity and other results with the In dopant concentration would be presented and discussed. (C) 2014 The Electrochemical Society.
