This comparative numerical simulation study investigates the electrical characteristics of two heterojunction thin-film solar cells based on Kësterites Copper Zinc Tin Sulfide. The study compared two solar cells with different structures, Zinc Oxide ZnO/Cadmium Sulfide CdS/Kësterites CZTS/Molybdenum Mo and Zinc Oxide ZnO/Zinc Sulfide ZnS/Kësterites CZTS/Molybdenum Mo, to determine which is more efficient in achieving maximum photovoltaic efficiency. The results showed that the ZnO/ZnS/CZTS/Mo solar cell is the better option, outperforming the CdS/CZTS/Mo solar cell in terms of short-circuit current density Jsc, open-circuit voltage Voc, form factor FF, and photovoltaic efficiency η. The study also investigated the effect of doping and layer thickness of CZTS and ZnS on photovoltaic parameters. The optimized ZnS/CZTS solar cell achieved an efficiency of 16.29% for ZnS and CZTS layer thicknesses of 0.02µm and 4μm, respectively, and doping concentrations of 1018 and 1016cm-3 , respectively. Overall, this study provides valuable insights for designing more efficient solar cells and optimizing their photovoltaic efficiency using Kësterites CZTS, CdS, and ZnS materials.

“…The resistivity values were compared with those obtained by Tanaka et al for CZTS thin lms obtained by the dip-coating method [38] and by Daranfed et al for CZTS thin lms synthesized by spray pyrolysis [39]. The obtained electrical resistivity was suitable for solar cell applications [40]. Furthermore, the electrical properties of sample C5 have not been uploaded owing to Cu-rich conditions; these latter conditions make the lm disadvantageously critical, full of dislocations, where the four points were unreachable.…”

Copper zinc tin sulfide (CZTS) thin films have been deposited by spin coating technique at various copper concentration ranging from 0.5M to 2.5M. The XRD patterns show the existence of the three main characteristic peaks of CZTS (112), (220) and (312), which indicate the formation of the kesterite structure of CZTS. Gap energy was calculated based on the derivation method using the absorbance data, and the values obtained vary from 1.46 eV to 1.58 eV depending on the copper molarities. Hall effect measurements were used to determine the conductivity, which in turn increased with the concentration of copper in the films. The results showed that the C3=1.5M exhibits higher crystallinity and better optical performance among the others. Finally, a theoretical efficiency of 11.6% was obtained by injecting the solar cell (CZTS/ZnS/S:ZnO) in SCAPS1D using the parameters obtained in this study. Under the adopted synthesis conditions, the theoretical simulation corroborated the experimental findings thus confirming that the synthesized material is a promising candidate for solar cell applications as an absorber layer.

“…They fabricated the CH 3 NH 3 PbI 3-x Cl x compound. Varying the value of x changes both the energy bandgap as well as the electron affinity of layer [91,92]. Thus, when such mixed compound is utilized to make an SC, its tunable bandgap and electron affinity value facilitates variation in the conduction and valance band offsets.…”

To achieve efficient solar cells, an in-depth review on significance of diffusion length enhancement is presented in this research work. We have focused on globally-adopted strategy of increasing diffusion length. The experimental pathways followed by various researchers to realize this strategy are deeply explored in this paper. The total of nine key-parameters that control and facilitate diffusion length enhancement are identified. Moreover, total of four parameters which are primarily influenced by diffusion length enhancement are listed. The underlying cause-&-effect mechanism pertaining to each parameter is discussed in-depth in this article. Furthermore, the comparison is performed between impact of electron and hole diffusion length enhancement on the device performance. The way to potentially implement this study for appropriate absorber layer selection is presented. Finally, a comparative study is performed on extent of influence of diffusion length enhancement technique to that of the band-offset optimization technique to achieve higher device performance. This rigorous analysis leads to discovery of the fact that diffusion length enhancement raises solar cell efficiency seven times as compared to that obtained by band offset optimization. Hence, significance of diffusion length enhancement for the pinnacle performance of solar cell is vividly revealed in this paper.
