“…The formation mechanism of nanorod arrays is attributed to the adsorption of carboxylate anions as capping agents on the side ends of the (Sb 4 Se 6 ) n ribbons inhibiting the lateral growth of ribbons. [ 54 , 55 , 56 ] The [ hk 1]‐oriented Sb 2 S 3 [ 57 , 58 ] and Sb 2 Se 3 [ 59 ] nanorod arrays are obtained by spin‐coating a seeding material on the substrate. Further mechanistic discussions will be presented in Section 4.5 .…”

“…Thus, a good lattice matching was found between the orthotropic [101]-oriented Sb 2 S 3 and the anatase [101]-oriented TiO 2 . Wang et al developed a seedassisted solution method for the pre-spin coated [hk1]-oriented Sb 2 S 3 seeding material on a polycrystalline TiO 2 nanoparticle film and prepared [hk1]-preferred oriented Sb 2 S 3 [57,58] and Sb 2 Se 3 [59] nanorod array films by repeating the spin-coating and annealing processes. Based on the above work, Liu et al prepared…”

The emerging antimony chalcogenide (Sb2(SxSe1−x)3, 0 ≤ x ≤ 1) semiconductors are featured as quasi‐1D structures comprising (Sb4S(e)6)n ribbons, this structural characteristic generates facet‐dependent properties such as directional charge transfer and trap states. In terms of carrier transport, proper control over the crystal nucleation and growth conditions can promote preferentially oriented growth of favorable crystal planes, thus enabling efficient electron transport along (Sb4S(e)6)n ribbons. Furthermore, an in‐depth understanding of the origin and impact of the crystal orientation of Sb2(SxSe1−x)3 films on the performance of corresponding photovoltaic devices is expected to lead to a breakthrough in power conversion efficiency. In fact, there are many studies on the orientation control of Sb2(SxSe1−x)3 colloidal nanomaterials. However, the synthesis of Sb2(SxSe1−x)3 thin films with controlled facets has recently been a focus in optoelectronic device applications. This work summarizes methodologies that are applied in the fabrication of preferentially oriented Sb2(SxSe1−x)3 films, including treatment strategies developed for crystal orientation engineering in each process. The mechanisms in the orientation control are thoroughly analyzed. An outlook on perspectives for the future development of Sb2(SxSe1−x)3 solar cells based on recent research and issues on orientation control is finally provided.
