Cu2MSnS4 (M = Co,Mn,Fe,Mg) are emerging as potential photovoltaic absorbers owing to their exceptional properties. However, a large open‐circuit voltage (VOC) deficit caused by the unfavorable band alignment with the toxic CdS buffer limits their overall efficiency. Therefore, identifying an appropriate alternative buffer is essential for improving performance. Herein, solar cell capacitance simulator in one dimension (SCAPS‐1D) is employed to theoretically design and analyze these emerging solar cells using TiS₂ as a substitute for CdS. The investigation focuses on various parameters, including buffer, absorber, and interface characteristics, to evaluate their impacts on performance. Remarkably, the highest efficiencies achieved with TiS₂ buffers are 27.02%, 27.04%, 30.04%, and 30.26% for Cu2MSnS4 (M = Co,Mn,Fe,Mg), respectively, surpassing CdS by 1.36, 1.76, 1.23, and 1.15 times. The high efficiencies obtained are associated with reduced electron barrier of −0.24 eV, −0.4 eV, −0.04 eV, and 0.08 eV at TiS2/Cu2MSnS4 (M = Co,Mn,Fe,Mg) interface, lower accumulation capacitance, significantly higher built‐in potentials (>1.2 V), lower VOC losses (<0.35 V) and improved recombination resistance in TiS₂ solar cells compared to CdS. Additionally, the study addresses the experimental challenges and strategies necessary for the practical fabrication of TiS2‐based solar cells, providing valuable insights for the photovoltaic community.

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.
