“…They revealed that annealing at 450 • C results in high crystalline films, with a decrease in optical band gap to 1.6 eV and improved electrical conductivity. On the other hand, Shaikh et al, studied the impact of annealing time on the properties of CZTS films, and demonstrated that longer annealing times leads to improvements in conductivity, light absorption, and mechanical stability [23]. The synthesis of CZTS and CZTSe thin films involves a meticulous exploration of several critical parameters, each influencing the properties of the resulting films.…”

Kesterite-based copper zinc tin sulfide (CZTS) and copper zinc tin selenide (CZTSe) thin films have attracted considerable attention as promising materials for sustainable and cost-effective thin-film solar cells. However, the successful integration of these materials into photovoltaic devices is hindered by the coexistence of secondary phases, which can significantly affect device performance and stability. This review article provides a comprehensive overview of recent progress and challenges in controlling secondary phases in kesterite CZTS and CZTSe thin films. Drawing from relevant studies, we discuss state-of-the-art strategies and techniques employed to mitigate the formation of secondary phases. These include a range of deposition methods, such as electrodeposition, sol-gel, spray pyrolysis, evaporation, pulsed laser deposition, and sputtering, each presenting distinct benefits in enhancing phase purity. This study highlights the importance of employing various characterization techniques, such as X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy, for the precise identification of secondary phases in CZTS and CZTSe thin films. Furthermore, the review discusses innovative strategies and techniques aimed at mitigating the occurrence of secondary phases, including process optimization, compositional tuning, and post-deposition treatments. These approaches offer promising avenues for enhancing the purity and performance of kesterite-based thin-film solar cells. Challenges and open questions in this field are addressed, and potential future research directions are proposed. By comprehensively analyzing recent advancements, this review contributes to a deeper understanding of secondary phase-related issues in kesterite CZT(S/Se) thin films, paving the way for enhanced performance and commercial viability of thin-film solar cell technologies.

“…The phase purity of the samples was confirmed using Raman spectroscopy with a 532 nm excitation wavelength. 61 Secondary phases like ZnS and Cu 2 SnS 3 may be present in CZTS films. CZTS and these phases had similar XRD patterns; hence, Raman spectroscopy was utilized.…”

Herein, the first paper for preparing Cu2ZnSnS4 film using EDTA as a complex agent by one-step hydrothermal method. The efficient Molybdenum oxide (MoO3) layer was also grown by the same step as preparing the Cu2ZnSnS4 film. The effects of different copper concentrations on the structural, optical, and electrical properties were studied. X-ray diffraction and Raman analyses confirmed the formation of polycrystalline kesterite phase Cu2ZnSnS4 films with preferred orientation along (112) plane and showed that structure property alters with copper concentration: at lower copper concentration single kesterite phase Cu2ZnSnS4 was formed, while with increasing copper concentration kesterite Cu2ZnSnS4 and secondary phases were formed. Field emission scanning electron microscopy revealed a mixture of micro-flower and a thin network of nanoflakes morphology. In addition, it showed as copper concentration changes the grain size of micro-flower and thickness of flakes change. UV-visible analysis showed high and broad absorbance spectra with high absorption coefficient values of more than 104 cm−1 in visible and infrared regions.also, predicted the band gap of single-phase Cu2ZnSnS4 film equal to 1.4 eV. Photoluminescence analysis demonstrated a single emission peak located at 1.55 eV which is quite near to the band gap of kesterite Cu2ZnSnS4. Hall measurement showed the single phase sample is a p-type semiconductor with a resistivity of 5 Ω cm, a charge carrier concentration of 7.5 × 1016 cm−3 and mobility of 16 cm2 Vs−1. Finally, a heterojunction solar cell was made with Mo foil/MoO3/CZTS/Zn0.35Cd0.65S/ZnO/Al configuration. A photovoltaic conversion efficiency of (2.17%) was attained under 100 mW cm−2 with an open-circuit voltage of (0.432) V, short-circuit current density of (13.4) mA cm−2 and a fill factor of (37.5%).
