“…A. J. Pal group managed to synthesize CFTS with SILAR method and achieved solar cell efficiency of 2.95% by replacing the CdS buffer layer with the Bi 2 S 3 buffer [160], which exhibits a more favorable band alignment at the interface as measured by scanning tunneling spectroscopy (STS) ( figure 15). As pure CFTS has a high conductivity, it is also used as counter electrode in DSSC solar cell [157,161]. Some usage in photoelectrochemical cells (PEC) [162] and n-type absorber in hybrid organic solar cell [163] have also been reported.…”

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.

“…in 2014 reported the PCE of Cu 2 FeSnS 4 (CFTS) thin film based DSSC to be 8.03% which is higher than that of Pt (7.57%) achieved by the same group . The high carrier mobility (11.44 cm 2 /V⋅s), lower charge transfer resistance at electrode/electrolyte interface, and high charge carrier density of the order of 10 16 favors CFTS to be another viable alternative to Pt ,.

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.
