“…Sharma et al [30] investigated the materials Cu 2 MgSnSe 4 and Cu 2 MgSnS 4 in two possible phases, kieserite and stannite, by replacing Zn with Mg. After replacing Zn with group IIA elements, the open-circuit voltage deficit was decreased by more than 100 mV [31]. In alternate studies, transition metals (TM) such as Mn, Co, Ni, and Fe [32] were used instead of zinc. M Zhou [33] and A Reshak [34] explored the chalcogenide photocatalyst Ba 2 ZnSe 3 , which is visible light sensitive.…”

Ternary chalcogenides are often studied for their remarkable heat resistance and flexible optical properties. We used the well-known density functional theory and examine the complicated connections between the various physical features of the exclusive GePtCh (Ch = S, Se, and Te) ternary chalcogenides. The valence band is formed by the hybridization of the Ge-s/p/d, Pt-s/p/d, and s-p, se-p, and Te-p orbitals in the energy range of -6.0 eV to 0 eV. The materials under consideration are confirmed as indirect bandgap materials with estimated energy gaps of 1.3 eV, 0.8 eV, and 0.2 eV, respectively. By substituting Se and Te for S reduced the bandgap in these materials. The complex dielectric function's components, absorption coefficients, real optical conductivity, energy loss functions, refractive index, reflectivity, and extinction coefficient, are studied and examined to identify their potential use in optoelectronic applications. The thermodynamic parameters of these ternary systems are calculated by employing the quasi-harmonic Debye model. The materials are suitable for thermoelectric applications, as evidenced by their considerable and outstanding thermoelectric properties. Among the materials, GePtTe possessed the highest absorption, indicating that it is a suitable material for the use in optoelectronic applications.

“…Antisite defects present in CZTS due to similar atomic size of zinc and copper atoms have hindered their efficiency improvement in recent years [15][16][17][18]. The zinc replacement in CZTS with various cations results in materials that have similar optical characteristics to CZTS material [19][20][21][22][23]. Among them, copper manganese tin sulfide (Cu 2 MnSnS 4 , i.e., CMTS) is a promising material due to its low cost, nontoxicity, high absorption coefficient (> 10 4 cm −1 ), and tunable bandgap between 1.2-1.5 eV [24][25][26][27][28][29].…”

The aim of this work is to study the photovoltaic performance of CMTS-based solar cell using solar cell capacitance simulator-1D. The use of ZrS2 as a buffer layer for CMTS-based solar cell is the novelty of this work. The impact of several parameters such as thickness, defect density, electron affinity, and doping concentration on the cell performances is investigated to improve cell performance. It is observed that these parameters impact significantly the solar cell performance. The optimized solar cell obtained an efficiency of 31.54% with an open-circuit voltage of 0.99 V, short-circuit current density of 36.44 mA/cm 2 , and fill factor of 87.69%. The results suggest guidelines for developing low-cost and highly efficient CMTS thin-film solar cells.

Herein, the 1D Solar Cell Capacitance Simulator software is used to perform numerical analysis of thin‐film solar cells with Cu2ZnSnS4, Cu2BaSnS4, Cu2FeSnS4, and Cu2MnSnS4 absorber layers. The main goal is to investigate the impact of parameters, such as absorber layer thickness, acceptor density, buffer layer, bandgap, and donor density, on the efficiency of these solar cells. The absorber layer investigation entails varying the thickness and the acceptor density to evaluate their influence on the efficiency of the solar cell. A new zinc oxide sulfide (Zn(O,S)) buffer layer is also introduced instead of the conventional cadmium sulfide (CdS) buffer layer. The Zn(O,S) bandgap and its donor density, which are investigated in terms of how they affect the efficiency of the solar cells, have been varied. The optimal values for the thickness of the absorber layer, acceptor density, and the bandgap of the buffer layer are calculated. Subsequently, the donor density is evaluated to find any potential defects that may affect the efficiency of the solar cell. These results confirm that Zn(O,S) can be utilized as a buffer layer. This study concludes that Cu2ZnSnS4, Cu2BaSnS4, and Cu2MnSnS4 absorber layers have superior efficiency in comparison with Cu2FeSnS4.
