摘要：

A novel idea that using chemical bath deposition-annealing route for preparing absorber films of the Cu2ZnSnS4-xSex solar cells with stacked layers (ZnS/Cu/SnS) was proposed and carried out in this study. The absorber layers fabricated by this new method were demonstrably proper for solar cell devices. The solar cells based on the as-synthesized Cu2ZnSnS4-xSex/Cu2ZnSnS4 layers showed high photoelectric transformation efficiency, nearly 3.0% and 2.2% with the large area 1.27 cm(2) and 1.80 cm(2), respectively. The new method introduced here based on chemical bath deposition without the complexity of vacuum equipment may provide an alternative approach to produce large area solar cells for practical application. In addition, during the deposition of the stacked layers, a new concept called Assistant Reduction Reaction was firstly carried out to deposit metallic Cu thin film on the SnS film, which acted as not only a substrate, but also an assistant reductive agent. If the present technique is properly extended, it is possible for the preparation of other metal thin films for practical application. (C) 2015 Elsevier B.V. All rights reserved.
