The synthesis of highly crystalline Cu2ZnSnSe4 (CZTSe) absorber films through two-stage process of the selenization of a sputtered metallic CZT precursor layers on Mo substrate followed by annealing under selenium vapor was a promising approach for fabricating high efficiency solar cells. In this study, CZTSe films have been characterized in detail using X-ray diffraction (XRD), scanning electron...
Precursors of the Cu2ZnSnSe4 (CZTSe) absorber were deposition on Mo/glass substrate by radio-frequency (RF) magnetron sputtering at room temperature. The precursors were converted into CZTSe absorber by annealing in the selenium vapors at the substrate temperature of 550°C. CZTSe films have been characterized in detail using X-ray diffraction (XRD), Raman spectroscopy, photo luminescence (PL), energy...
Hexagonally patterned quasi-one-dimensional (quasi-1D) ZnO nanowire arrays have been successfully synthesized through a simple vapor transport process without metal catalysts. With the aid of a polystyrene microsphere self-assembled monolayer, sol-gel-derived ZnO thin film was used as the periodic nucleation sites for nanowire growth. High-quality quasi-1D ZnO nanowires were demonstrated via structural...
Nanostructured ZnO samples on Si(100) and glass substrates have been synthesized by simple chemical solution method with post-thermal treatments. UV-vis spectrum, Hall measurement, and photoluminescence and scanning electron microscopy (SEM) have been used to characterize nanostructured ZnO thin films at various annealing temperatures. Post-thermal treatment does not only modify the surface morphology...
In this article, we report the improvement on the output-power stability of AlGaInP/GaAs LEDs by hydrogen annealing. Compared with those samples annealed in AsH3 ambient, the variation of hydrogen-annealed LED's output-power is well controlled in the range of 0.5%~1.5%.
