Kesterite based on Cu2ZnSnS4 composition is considered as a promising absorber material for the next generation of photovoltaics due to raw materials abundance and low toxicity. Developing superstrate architecture using kesterite an could be key better performance, which allows new ways engineering formation thin film. In this work, we study effects sulfurization temperature crystallization fil...

The objective of this work is to introduce a different technique existing studies that determine the stoichiometric ratios thin CZTS structures. To end, targets were propagated by sol-gel process and later RBS PIXE spectra achieved irradiating these samples with protons 3.034 MeV energy into microbeam chamber. spectrum was taken detector collected IGe SDD detectors. As calibration performed fix...

The effects of using different counter electrode metal sulfides on the performances of solar cells made with CdS/CdSe/ZnS quantum dots co-sensitized onto hierarchical TiO2 spheres (HTSs) used as photo-electrode are reported. The HTS in the QDSSCs is composed of an assembly of numerous TiO2 spheres made by the solvolthermal method. The photoelectrical performance of HTS/CdS/CdSe/ZnS coupled to C...

The classical interpolation-based Polar Format Algorithm (PFA) for spotlight synthetic aperture radar (SAR) results in numerous computation load, which, reduces processing speed and increase system complexity. To decrease computation load, this paper proposes a novel non-interpolation PFA algorithm for sensor flying along non-lineal flight trajectories, which are specially designed curves in co...
