Abstract

Using a commercially viable and environmentally friendly aqueous chemical method, Cu2ZnSnS4 films with different stacked structure precursors are prepared on flexible Mo foil substrates, and then solar cells with the structure of Ag/AZO/i-ZnO/CdS/CZTS/Mo foil are fabricated. A comparative study reveals that the absorber from the Cu2SnSx/ZnS/Mo precursor shows preferable crystallinity and morphology than that from ZnS/Cu2SnSx/Mo precursor. Accordingly, the device based on the former absorber yields better performance, demonstrating an efficiency of 2.42%. Issues involved microstructure and secondary phases that limit the performance of the device are discussed.
