Improving the Device Performance of CZTSSe Thin-Film Solar Cells via Indium Doping.

Cation incorporation emerges as a promising approach for improving the performance of the kesterite CuZnSn(S,Se) (CZTSSe) device. Herein, we report indium (In) doping using the chemical bath deposition (CBD) technique to enhance the optoelectronic properties of CZTSSe thin-film solar cells (TFSCs). To incorporate a small amount of the In element into the CZTSSe absorber thin films, an ultrathin (<10 nm) layer of InS is deposited on soft-annealed precursor (Zn-Sn-Cu) thin films prior to the sulfo-selenization process.

InO nanocapsules for rapid photodegradation of crystal violet dye under sunlight.

We report, a shape controlled novel synthesis of Indium oxide (InO) nanocapsule using biogenic reflux method. The InO samples were obtained through optimization of the concentration of sodium citrate, which played a significant role to tune the size of nanocapsules. All synthesized InO samples were characterized by using X-ray diffraction (XRD), infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and selected area electron diffraction (SAED).
