The research focused on the hydrothermal synthesis of a material based Kesterite structure Cu2ZnSnS4 (CZTS). For this purpose, component cations, in concentrations 1.0 molL-1, were placed steel autoclave under different temperatures conditions (200, 220, 240, 260 and 280°C) for 32 h. After, solids calcined at 400°C 2 UV-VIS results showed that materials had strong tendency to absorb region 600-...

Microwave synthesized nano-sized Cu2ZnSnS4 (CZTS) powder was irradiated with 6 MeV electrons, to investigate stability under radiation. The structural, optical, vibrational and morphological properties were explored using X-ray diffraction, UV–Visible spectroscopy, Raman spectroscopy scanning electron microscope (SEM). sample shows significant change in when compared the pristine sample. peak b...

Undoped and Sb-doped, Cu2ZnSnS4 (CZTS) thin films have been synthesized on ordinary glass slides using the sol-gel spin coating method. The effect of variation in Sb doping concentration structural, optical, surface morphological characteristics CZTS has investigated. XRD analysis reported that these samples show a kesterite phase which is further confirmed by Raman spectra. crystallite size fo...

Joglekar, Chinmay S. M.S.Ch.E., Purdue University, May 2014. CZTSSe Thin Film Solar Cells: Surface Treatments. Major Professor: Rakesh Agrawal. Chalcopyrite semiconducting materials, specifically CZTS, are a promising alternative to traditional silicon solar cell technology. Because of the high absorption coefficient; films of the order of 1 μm thickness are sufficient for the fabrication of so...

This project deals with theoretical modeling and calculation of the properties of defects in CIGS and CZTS absorber materials. The long term goal is predictive models for defect evolution, impurity kinetics and phase transformation in these materials to enable optimization of fabrication processes for maximum cell efficiency and reliability. A tool for calculation of the concentrations of domin...

We present an optical simulation of a solar cell employing core (Si) /shell (Kesterite Cu2ZnSnS4 (CZTS) or/and Cu2ZnSnSe4 CZTSe) vertically-aligned nanowire array. The method the is rigorous coupled wave analysis. In first stage, we studied case where shell composed only CZTS or CZTSe. A larger absorptance CZTSe led to value ideal short circuit current (41 mA/cm2) in than (24 mA/cm2). second av...

Efficient copper based thin film solar cells usually use inorganic n-type semiconductor material CdS as the buffer layer. Therefore, interface quality and energy band matching between layer absorption are crucial to collection utilization of carriers. Heat treatment can promote mutual diffusion elements, migration ions in material, change defect state, appropriate temperature will Cu-Zn orderin...

Hole transport material (HTM) is a major component of perovskite solar cells (PSCs). PEDOT: PSS, an organic HTM, widely used in inverted (p-i-n) PSCs. While PSS unstable, expensive and it's acidic nature could deteriorate the absorber. Copper zinc tin sulphide (CZTS), inorganic semiconductor can be as HTM due to its properties such low cost, ease synthesis high hole mobility. In this work, devi...
