With a high absorption coefficient and tunable bandgap CZTS (Copper Zinc Tin Sulfide) makes it suitable for photovoltaic applications. Present paper deals with the simulation and modeling of CZTS-based solar cells using tungsten disulfide (WS2) as the buffer layer and CZTS2 as the back surface field (BSF) layer to study the performance of the solar cell. Considering different physical and geometrical parameters such as thickness, acceptor density, interfacial defect density, and metal contact work functions the device calibration has been done. The temperature is varied from 300 K to 400 k to study the impact on device performance. The C-V and 1/C2 plot is presented to calculate the built-in voltage for the device. The series (Rs) and shunt (Rsh) resistance of 1 and 106 ohm.cm2 were kept throughout the simulation. The optimized thickness for the absorber, BSF, buffer, and window layers are 800 nm, 140 nm, 30 nm, and 90 nm respectively. The obtained results are validated using the experimental results available in the literature. Varying the values of different parameters, the optimal efficiency of 26 % was reported in this work. Contrary to conventional solar cells, which contain expensive and toxic elements, WS2 may be a good option as a buffer layer in CZTS solar cells.

“…4,5 Recently, CZTS scs have shown outstanding progress with power conversion efficiency (PCE) reaching up to 12.6%, which is comparable to other thin-film scs technologies such as CdTe and CIGS. 6 Also, CZTS scs have several advantages over other thin-film sc technologies. First, CZTS consists of earth-abundant elements, which eliminates concerns about supply chain constraints and environmental issues associated with toxic materials.…”

The present paper deals with the photovoltaic performance‐based numerical evaluation of copper–zinc–tin–sulfur (CZTS) solar cells embedded with CZTSe as a back surface field (BSF) layer. CZTS has been considered a leading candidate for the fabrication of solar devices owing to its availability and absence of toxicity. Adding a BSF layer to a solar device is a novel way to boost efficiency. It reduces the recombination of the carriers at the back surface, thus increasing the overall current output of the solar cells. SCAPS 1D simulator is used to study the impact of several parameters on electrical properties like temperature, the thickness of the CZTS layer, acceptor doping concentration, and the impact of series and shunt resistances. Considering the optimized parameters in each layer of the solar cells, this work delivers 24.7% efficiency with the BSF layer, which is 8% more than that without the BSF layer. The results of this modeling will facilitate researchers to fabricate a highly efficient CZTS solar cell.
