“…Kesterite materials have high light absorption coefficient a ∼ 10 4 cm -1 and optimal band gap E g ∼ 1.0-1.5. However, the maximum efficiency value of solar cells based on CZTSSe is still 12.6% [1], which is far from the theoretically possible 32% [2]. The reason for this may be the presence of secondary phases in the films or molybdenum sulfide at the kesterite/Mo interface and, in general, the relatively less studied formation mechanism of the final films.…”

The use of liquid-phase method from DMSO solutions for synthesis of CZTS thin film materials

et al. 2019

The possibility of synthesis of CZTS thin films on glass substrates from DMSO precursor solutions containing various quantity of copper ions was investigated. The dependence of composition of final CZTS compounds obtained from precursor solutions with different copper ion concentration in DMSO was shown. It was obtained that with the introduction of a low additive of copper ion concentration one can synthesize CZTS thin films with kesterite structure as well as with secondary phases (tin sulfides of SnS, Sn2S3). The increase of the concentration of copper ions in DMSO precursor solution promotes the formation of CZTS thin films with kesterite phase and the minimum content of impurities.

“…Stannite is present in samples prepared at low temperatures since it has slightly higher energy formation. Kesterite instead, has a lower energy formation and will be the predominant phase when it is prepared at sufficiently high temperatures (Das et al, 2016;Rakitin and Novikov, 2016).…”

Kesterite materials based on Cu2ZnSnS4 composition are considered as promising absorber material for the next generation of photovoltaics due to raw materials abundance and low toxicity. Developing a superstrate architecture using kesterite as an absorber could be the key to a better performance, which allows new ways of engineering the formation of a kesterite thin film. In this work, we study the effects of the sulfurization temperature on the crystallization of kesterite film when is fabricated in a superstrate architecture, and how this affects the performance of a solar cell. We noted that the temperature affects the final composition of the absorber due to cadmium diffusion at 500 ºC from the CdS layer, while the temperature above 530 ºC is essential for a complete Zn incorporation into the crystal structure. The crystallinity is highly affected, and a temperature of 550 ºC is found to be favorable for the crystal growth, and the fabricated device gave improved performance. Impedance spectroscopy measurements suggest the performance enhancement is due to the reduction of defects and an increase of the depletion width in the p-n junction.

“…In recent years, intensive research effort has been concentrated on alternative power generation technologies, in particular on the fabrication of solar cells [1]. Promising inorganic materials for solar cells include solid solutions based on the Cu 2 ZnSnS 4 (CZTS) and Cu 2 ZnSnS 4 (CZTSe) compounds with the kesterite structure [1]. However, the efficiency of solar cells based on them is just 12%, whereas their theoretically possible efficiency is 30% [2].…”

“…The low efficiency of such solar cells can probably be understood in terms of the fundamental features of the crystal structures of CZTS and CZTSe. Owing to the identical electronic structures of the Zn 2+ and Cu + ions (18-electron shell), the similar atomic numbers of copper and zinc (29 and 30, respectively), and the identical ionic radii of Zn 2+ and Cu + [3], the crystal lattice of kesterite Cu 2 ZnSnS 4 contains a large number of Cu Zn and Zn Cu antisite defects [1,4], which act as traps for photogenerated current carriers [5]. Because of this, there is considerable scientific and practical interest in magnesium substitution for zinc in the structure of Cu 2 ZnSnSe 4 .…”

Crystallographic and Luminescence Characteristics of the Cu2MgSnSe4 Quaternary Compound and Cu2 – xMgSnSe4 (0 < x ≤ 0.15) Copper-Deficient Solid Solutions

Crystallographic characteristics of the Cu 2 MgSnSe 4 quaternary compound and Cu 2 -x MgSnSe 4 (0 < x ≤ 0.15) copper-deficient solid solutions have been determined for the first time. It has been shown that the band peaking at 1.39 eV in the 78-K cathodoluminescence spectrum of Cu 2 MgSnSe 4 is most likely due to Cu Mg and Mg Cu antisite defects resulting from exchange of atoms between the copper and magnesium sublattices in the kesterite structure and that the spectra of Cu 2 -x MgSnSe 4 contain, in addition to the 1.39-eV band, a band peaking at 1.34 eV, which is due to Cu 2+ • V Cu defect associates.
