“…Since the first synthesis of a CAS nanomaterial by the current authors, investigations into this class of materials have continued to expand. Numerous investigations have been conducted into the dominant phases of CAS, namely, tetrahedrite (Cu 12 Sb 4 S 13 ), − famatinite (Cu 3 SbS 4 ), , and chalcostibite (CuSbS 2 ), − as well as few reports on the synthesis and characterization of skinnerite (Cu 3 SbS 3 ). , All these phases are p-type semiconductors with high absorption coefficients (∼10 4 to 10 5 cm –1 ), direct bulk band gaps that vary between ∼1 and 1.8 eV, modest hole mobilities between 10 and 70 cm 2 /V·s, ,,, and good defect tolerances. , Collectively, these properties make them suitable candidates for vis–near-infrared (NIR) photodetectors or solar absorber layers in PV devices.…”

“…However, up to now the efficiencies of TF solar cells with CuSbS 2 absorbers remain close to 3% [ 16 ]. A variety of physical and chemical methods have been used for the synthesis of CuSbS 2 absorbers, including sputtering, electrodeposition, chemical bath deposition, spray pyrolysis deposition and advanced powder technologies [ 11 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. Within them, the use mechanochemical synthesis (MCS) process, a solid-state synthesis route using high-energy ball mills, is being considered as a faster, scalable and environmentally friendly technology than the conventional processing routes for producing chalcogenides compounds [ 17 , 21 , 29 , 30 , 31 ].…”

One of the areas of research on materials for thin-film solar cells focuses on replacing In and Ga with more earth-abundant elements. In that respect, chalcostibite (CuSbS2) is being considered as a promising environmentally friendly and cost-effective photovoltaic absorber material. In the present work, single CuSbS2 phase was synthesized directly by a short-duration (2 h) mechanochemical-synthesis step starting from mixtures of elemental powders. X-ray diffraction analysis of the synthesized CuSbS2 powders revealed a good agreement with the orthorhombic chalcostibite phase, space group Pnma, and a crystallite size of 26 nm. Particle-size characterization revealed a multimodal distribution with a median diameter ranging from of 2.93 μm to 3.10 μm. The thermal stability of the synthesized CuSbS2 powders was evaluated by thermogravimetry and differential thermal analysis. No phase change was observed by heat-treating the mechanochemically synthesized powders at 350 °C for 24 h. By UV-VIS-NIR spectroscopy the optical band gap was determined to be 1.41 eV, suggesting that the mechanochemically synthesized CuSbS2 can be considered suitable to be used as absorber materials. Overall, the results show that the mechanochemical process is a viable route for the synthesis of materials for photovoltaic applications.

“…Several solution-based NP film fabrication methods are available, including drop-casting, dip-casting, spin-coating, spray-coating, and injection printing. In addition, the process of electrophoretic deposition (EPD) is an emerging technique for the fabrication of NP films from colloidal NPs [ 9 , 11 , 12 , 13 , 14 ]. This process has various advantages, such as strong adhesion of NPs to the substrate and a wide range of applicable materials for both NPs and substrates.…”

Electrophoretic Deposition of Aged and Charge Controlled Colloidal Copper Sulfide Nanoparticles

et al. 2021

Colloidal nanoparticles (NPs) have been recently spotlighted as building blocks for various nanostructured devices. Their collective properties have been exhibited by arranging them on a substrate to form assembled NPs. In particular, electrophoretic deposition (EPD) is an emerging fabrication method for such nanostructured films. To maximize the benefits of this method, further studies are required to fully elucidate the key parameters that influence the NP deposition. Herein, two key parameters are examined, namely: (i) the aging of colloidal NPs and (ii) the charge formation by surface ligands. The aging of Cu2-xS NPs changes the charge states, thus leading to different NP deposition behaviors. The SEM images of NP films, dynamic light scattering, and zeta potential results demonstrated that the charge control and restoration of interparticle interactions for aged NPs were achieved via simple ligand engineering. The charge control of colloidal NPs was found to be more dominant than the influence of aging, which can alter the surface charges of the NPs. The present results thus reveal that the charge formation on the colloidal NPs, which depends on the surface ligands, is an important controllable parameter in EPD.
