“…77 Xiang, in work on Cu(In,Ga)Se 2 (CIGS), identifies Cu 3 SbSe 3 as an important intermediate. 78 It is used similarly with Cu 2 ZnSnS 4 (CZTS) 79 in which it promotes grain growth, although Sb 2 S 3 is more effective.…”

“…The formation of NPs generally includes two steps, namely the nucleation step and the crystalline growth step [ 40 , 41 ]. Previous studies [ 26 , 42 , 43 ] consistently indicate that CIGS NPs were formed in two steps: (1) the formation of Cu-S crystal nuclei via the rapid reaction between Cu + and S 2− ; and (2) the incorporation of indium and gallium into the Cu-S crystal nuclei through the diffusion and/or cation exchanging. In addition, the crystal structure of final CIGS NPs may mainly depend on the structure of Cu-S nuclei [ 25 , 35 , 44 ].…”

“…In the past two decades, many efforts have been made to synthesize the chalcogenide NPs with desired properties for photovoltaic application [ 15 – 21 ]. Phase control is one of the most important point for the synthesis of chalcogenide NPs because their optoelectronic properties depend on the crystal structure [ 22 – 26 ]. According to literatures [ 27 – 29 ], CIGS may have three polymorphs: a thermodynamically stable phase with tetragonal chalcopyrite (CH) structure and two metastable phases with cubic zincblende (ZB) structure and hexagonal wurtzite (WZ) structure, respectively.…”

I-III-VI2 compounds have shown great interests in the application of functional semiconductors. Among them, Cu(In,Ga)S2 has been a promising candidate due to its excellent optoelectronic properties. Although the polymorphs of Cu(In,Ga)S2 have been attracted extensive attentions, the efforts to developing the methodologies for phase-controlled synthesis of them are rare. In this paper, we reported a phase-selective synthesis of CIGS nanoparticles with metastable phases via simply changing the composition of solvents. For the wet chemistry synthesis, the microstructure of the initial nuclei is decisive to the crystal structure of final products. In the formation of Cu(In,Ga)S2, the solvent environment is the key factor, which could affect the coordination of monomers and influence the thermodynamic conditions of Cu-S nucleation. Moreover, wurtzite and zincblende Cu(In,Ga)S2 nanoparticles are selectively prepared by choosing pure en or its mixture with deionized water as reaction solvent. The as-synthesized wurtzite Cu(In,Ga)S2 possess a band gap of 1.6 eV and a carrier mobility of 4.85 cm2/Vs, which indicates its potential to construct a heterojunction with hexagonal-structured CdS for solar cells.Electronic supplementary materialThe online version of this article (10.1186/s11671-018-2781-1) contains supplementary material, which is available to authorized users.

“…Several strategies to promote grain growth and to reduce the process temperature have been attempted. These strategies include the incorporation of sodium [8], copper selenide nanocrystals [16], or antimony [17,18] in the absorber layer and the use of a multi-step selenization process [19,20]. In this work, we systematically optimized the ink formulation and spray deposition conditions to produce highly homogeneous, smooth, and crack-free CuIn 1Àx Ga x S 2 (CIGS) layers from nanoparticle-based inks.…”

To produce smooth, crack-free, and highly crystalline absorber layers are the main challenges in the fabrication of thin film solar cells using nanoparticle-based solution-processing technologies. In this work, we report on the optimization of the spray deposition parameters to produce highly homogeneous CuIn 1Àx Ga x S 2 thin films with controlled thickness using nanoparticle-based inks. We further explore the use of inorganic ligand exchange strategies to introduce metal ions able to promote crystallization during the selenization of the layers, removing structural defects and grain boundaries that potentially act as recombination centers.
