[IEEE 2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT) - Dhaka, Bangladesh (2019.5.3-2019.5.5)] 2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT) - An Efficient CZTS Solar Cell from Numerical Analysis
摘要： The Copper Zinc Tin Sulfide (CZTS) is considered as one of the promising semiconductor materials in Kesterite family for potential solar cells absorber material. This work focuses on the numerical model and simulation of efficient CZTS based thin-film solar cell. Popular thin-film solar cell simulator wxAMPS was used for simulation of (Al:ZnO/i-ZnO/CdS/CZTS/Mo)structured solar cell and the effects of different layer properties on cell performance parameters were analyzed. An optimized cell with 15.84% (%FF=72.86, Voc=0.78Volt and Jsc=27.98 mA/cm2) energy conversion efficiency has proposed. The temperature coefficient (TC) of 0.02%/○C had shown the higher stability of the proposed cell. All of the simulated results had encouraged towards fabrication of high performance thin-film CZTS solar cells.

[IEEE 2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE) - Swat, Pakistan (2019.7.24-2019.7.25)] 2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE) - Modelling of Highly Efficient Copper Zinc Tin Sulphide (CZTS) Solar Cell for Performance Improvement
摘要： Low stability, less efficiency and high cost material of the solar cell make its commercialization and manufacturing less point of attention for many researcher and industrial investor. However, the main focus of this work is to compare the investigated material i.e., CZTS with existing materials i.e., amorphous, CIGS and perovskite solar cells with respect to efficiency, cost and stability as it is one of the keen interests in photovoltaic (PV) research field. In this paper, we have presented a highly efficient, highly stable and less costly thin film solar cell with novel material i.e., Copper Zinc Tin Sulphide (CZTS) that holds a conversion efficiency, η of 18.68% with supporting short current density, Jsc= 25.258mA/cm2, open circuit voltage, Voc=0.8787 V and fill factor, FF=84.17%. Different window layer materials along with various buffer layer materials is tested and founded that fluorine tin oxide (FTO) and Indium sulphide (In2S3) are best performing candidates among all other materials. Moreover, effect of high temperature on CZTS electrical parameter is analyzed and drop in the η is observed when the temperature of the device is increased.

The phase optimization, optical and electrical properties of kesterite Cu<sub>2</sub>ZnSnS<sub>4</sub> thin film prepared by single target RF magnetron sputtering technique for solar cell application.
摘要： Cu2ZnSnS4 (CZTS) thin film was prepared by RF sputtering technique from a single quaternary target by optimizing RF power, in-situ substrate temperature and post deposition annealing temperature. The single phase formation of crystalline CZTS thin film has been verified at a particular optimized condition by characterizing through X-ray diffraction, Raman selected area electron diffraction study. The surface properties such as particle size, shape and roughness and elemental composition of amorphous and crystalline phase of CZTS studied by atomic force microscope, scanning electron microscope and energy dispersive analysis of x-rays. The optical absorption and photoluminescence studies of post-deposition annealed film prove the defect free and single phase CZTS formation. The band gap calculation for crystalline CZTS showed band gap of 1.49eV calculated from the Tauc plot. The electrical properties of optimized CZTS thin film has been studied from Hall effect measurement showing P-type conductivity with better carrier concentration and Hall mobility.
