“…Recently, as the use of energy sources from the society increases, the world facing is more problems with nonrenewable energy sources. The researchers are working on to find renewable energy sources, in particular, photovoltaic system, where the sun acts as the source of the light radiations. − The Cu 2 ZnSn(S,Se) 4 (CZTSSe) thin-film-based solar cell technology has attracted great interest because of its abundant availability of elements at low cost. The Cu 2 ZnSn(S 1– x Se x ) 4 (CZTSSe) thin films provide a high optical absorption coefficient (α) equal to the Cu(InGa)Se 2 (CIGS)-based solar cells. , The CZTSSe film material is a promising alternative for CIGS materials because of the cost-effectiveness of constituted elements as compared to noble metals In and Ga and similar band gap energy materials.…”

Recently, deposition of Cu 2 ZnSn(S 1−x Se x ) 4 (CZTSSe) thin films directly onto substrates via a cost-effective hydrothermal route has become a promising approach for their further development. We investigated the influence of the Se 2− ion content on the growth and optoelectronic properties of CZTSSe thin films. The synthesized CZTSSe nanocrystalline films showed considerable refining in their optoelectronic and photovoltaic properties. The optical absorption of CZTSSe films revealed that the band gap energy decreases from 1.5 to 1.42 eV with increment in the Se 2− ion concentration. Structural analysis confirms the improvement in the crystallinity with the kesterite crystal structure, which was also validated by ( 112) plane shifting with varying Se 2− ion concentration. Surface morphological and structural analyses confirm the formation of a highly uniform, well-crystalline, and compactly interconnected nanosphere-like morphology. Compositional analysis confirms that the CZTSSe film shows desired stoichiometric ratios with Cu, Zn, Sn, S, and Se in +1, +2, +4, −2, and −2 oxidation states, respectively, in Cu 2 ZnSn(S 1−x Se x ) 4 compositions. The promising composition is observed for Cu 2 ZnSn(S 1−x Se x ) 4 films with x = 0.075 Se-ion concentration. Photoelectrochemical solar cells assembled for the CZTSSe photoelectrode exhibited a current density (J sc ) of 4.64 mA/cm 2 and an open-circuit voltage (V oc ) of 542 mV, leading to a photoconversion efficiency of 3.62%. Our electrochemical impedance spectroscopy suggests lower values of charge-transfer resistance (R ct ) generated at the photoelectrode−electrolyte interface, which is in well agreement with photoelectrochemical solar cell performance.

Cu2ZnSnS4 is a promising material for low-cost thin-film solar cells. This paper reports a new approach to fabricating a solar cell using a Superstrate and Substrate configuration. We utilized a non-vacuum deposition process to deposit Copper Zinc Tin Sulfate (CZTS) and Cadmium Sulphate (CdS) on a glass substrate. To achieve this, we adopted the sol-gel spin coating method for CZTS and the Chemical Bath Deposition (CBD) method for the CdS layer. The solar cell has two structures: ITO/Cu2ZnSnS4/CdS/Ag for substrate configuration and ITO/CdS/Cu2ZnSnS4/Ag for superstrate configuration. The Cu/(Zn+Sn) atomic ratio was set to 0.86, while Zn/Sn was set to 1.25. Our CZTS/CdS solar cell achieved a 48.7 × 10-6 % power conversion efficiency with a 1.40 eV band gap and 98.71 % external quantum efficiency at 373 nm for the superstrate configuration. For the substrate configuration, the power conversion efficiency was 19.0 × 10-6 % with a 1.49 eV bandgap and 95.74 % external quantum efficiency at 321 nm. Based on the results presented in the text, the CZTS solar cell with a superstrate configuration achieved a higher power conversion efficiency and external quantum efficiency than the substrate configuration. The superstrate configuration allowed for better light absorption in the CZTS layer and reduced the reflection of light back into the substrate. This configuration also prevented the back diffusion of CdS into CZTS and improved the electrical performance of the solar cell. Therefore, the superstrate configuration is more efficient than the substrate configuration for CZTS solar cells.
