“…Unlike CZTS, CFTS is more stable in stannite crystal structure (ST) with an I-42m space group which shows less cationic disorder from the kesterite structure [155]. CFTS thin films have been fabricated by various methods, such as solvothermal [142], hot injection method [141], molecular method [156], spray pyrolysis [157], and mostly focused on its magnetic properties. Even though CFTS exhibit a band gap between 1-1.5 eV and high absorption coefficient (10 4 cm −1 ) in the visible spectrum range [158], there are not many reported CFTS photovoltaic devices in literature.…”

“…As for the Fe alloying in CZTS, both of Fe 2+ (0.66 Å) and Zn 2+ (0.64 Å) have similar ionic radii, which enables a solid solubility in the Cu 2 Zn x Fe 1−x SnS 4 (CZFTS) [18]. There are few studies about CZFTS thin film properties which shows transformation from kesterite to stannite and increase in band gap (ranging from 1.35 eV to 1.7 eV) as the amount of Fe increases [156,[164][165][166]. However, a combinatorial study using spray coating showed a strong detrimental effect on quasi-Fermi level splitting (QLFS) in Cu 2 Zn x Fe 1−x Sn(S,Se) 4 even at low concentrations of Fe [167].…”

Attempts to improve the efficiency of kesterite solar cells by changing the intrinsic stoichiometry have not helped to boost the device efficiency beyond the current record of 12.6%. In this light, the addition of extrinsic elements to the Cu 2 ZnSn(S,Se) 4 matrix in various quantities has emerged as a popular topic aiming to ameliorate electronic properties of the solar cell absorbers. This article reviews extrinsic doping and alloying concepts for kesterite absorbers with the focus on those that do not alter the parent zinc-blende derived kesterite structure. The latest state-of-the-art of possible extrinsic elements is presented in the order of groups of the periodic table. The highest reported solar cell efficiencies for each extrinsic dopant are tabulated at the end. Several dopants like alkali elements and substitutional alloying with Ag, Cd or Ge have been shown to improve the device performance of kesterite solar cells as compared to the nominally undoped references, although it is often difficult to differentiate between pure electronic effects and other possible influences such as changes in the crystallization path, deviations in matrix composition and presence of alkali dopants coming from the substrates. The review is concluded with a suggestion to intensify efforts for identifying intrinsic defects that negatively affect electronic properties of the kesterite absorbers, and, if identified, to test extrinsic strategies that may compensate these defects. Characterization techniques must be developed and widely used to reliably access semiconductor absorber metrics such as the quasi-Fermi level splitting, defect concentration and their energetic position, and carrier lifetime in order to assist in search for effective doping/alloying strategies.

Cu-based quaternary chalcogenide semiconductors have been attractive materials in many aspects since the last decade. Most of the scientific literature about quaternary chalcogenides is dedicated to photovoltaic (PV) research with no astonishment as the material initially emerged as a costeffective replacement of expensive Si for PV applications. These materials possess all the important properties such as, abundant and non-toxic constituent elements, efficient charge transport, optimum band gap, and high absorption coefficient for being an efficient PV material in either thin film or nanoparticle form. However, in the recent few years, a new range of quaternary materials Cu 2 M I M II X 4 (where, M I =Zn, Ni, Co, Fe, Mn, Cd and Hg; M II =Si, Sn and Ge and X=S and/or Se) have evolved and found applications in thermoelectrics, photocatalysis and photoelectrocatalysis, sensors and bat-teries etc. The combination of properties exhibited by these quaternary chalcogenides such as optical and electric, optical and magnetic, electric and thermal makes them potential materials, which could be utilized in multiple applications. Although the PV properties of these quaternary chalcogenides has been discussed earlier in many reports, the other versatile applications of the material have not been reviewed yet. The present article sheds light on the multifunctional aspects of various new Cu-based quaternary chalcogenides, their synthesis, effect of doping on their properties, and then elaborating the discussion on their chemical and physical properties that are helpful in different applications along with photovoltaics. Here, we discuss synthetic methods bestowing enhanced features and also summarize their achieved efficiency in recent years. Scheme 1.

“…The development of a method for controlling the phase of the obtained CZTS would be a major step toward commercializing CZTS. We have previously reported the synthesis of CZTS and Cu 2 Zn 1-x Fe x SnS 4 nanoparticles and thin films from the decomposition of dithiocarbamate single-source precursors (SSPs) [41][42][43].…”
