One of the main components of the worldwide transition to sustainable energy is solar cells, usually referred to as photovoltaics. By converting sunlight into power, they lessen their reliance on fossil fuels and the release of greenhouse gases. Because solar cells are decentralized, distributed energy systems may be developed, which increases the efficiency of the cells. Chalcogenide perovskites have drawn interest due to their potential in solar energy conversion since they provide distinctive optoelectronic characteristics and stability. But high temperatures and lengthy reaction periods make it difficult to synthesise and process them. Therefore, we present the inaugural numerical simulation using SCAPS-1D for emerging inorganic BaZrS3/CuO heterojunction solar cells. This study delves into the behaviour of diverse parameters in photovoltaic devices, encompassing efficiency (η) values, short-circuit current density (Jsc), fill factor (FF), and open-circuit voltage (Voc). Additionally, we thoroughly examine the impact of window and absorber layer thickness, carrier concentration, and bandgap on the fundamental characteristics of solar cells. Our findings showcase the attainment of the highest efficiency (η) values, reaching 27.3% for our modelled devices, accompanied by Jsc values of 40.5 mA/cm2, Voc value of 0.79 V, and FF value of 85.2. The efficiency (η) values are chiefly influenced by the combined effects of Voc, Jsc, and FF values. This optimal efficiency was achieved with CuO thickness, band gap, and carrier concentration set at 5 µm, 1.05 eV, and above 1019 cm−3, respectively. In comparison, the optimal parameters for BaZrS3 include a thickness of 1 µm, a carrier concentration below 1020 cm−3, and a band gap less than 1.6 eV. Therefore, in the near future, the present simulation will simultaneously provide up an entirely novel field for the less defective perovskite solar cell.

“…Solar cells are a promising renewable energy source as they are an environmentally eco-friendly method to reduce CO 2 emissions and satisfy the demand for green energy [1][2][3]. Extensive research is being conducted on copper-based quaternary chalcogenide semiconductors as a cost-effective substitute to conventional absorber materials in solar cells due to their direct bandgap and abundance in availability [4][5][6].…”

“…Recently, transition metal dichalcogenides (TMDCs) have been used for various applications, especially in photodetectors [36,37] and solar cells [38] instead of conventional materials due to large band-edge excitation produced by d-d transition situated at a metal site [2]. Zirconium disulfide (ZrS 2 ), a group IV of TMDCs, shows a low lattice mismatch with absorber materials due to the van der Waals force [38,39].…”

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.

SnS, Sb2Se3, Cu2SnS3, CuSb(S,Se)2, and Cu2BaSn(S,Se)4 are emerging as promising light absorbers for thin‐film photovoltaics due to their extraordinary optoelectronic properties. However, improper band alignment with the buffer and large open‐circuit voltage (VOC) deficit limits their power conversion efficiencies (PCE). Therefore, finding a suitable buffer that overcomes these obstacles is crucial. Herein, ZrS2 as an alternative buffer for the aforementioned emerging thin‐film solar cells using SCAPS‐1D is proposed. The important ZrS2 parameters are optimized, including bandgap, thickness, carrier concentration, and defect density. Interestingly, ZrS2 behaves as a degenerate semiconductor at carrier concentrations >1E17 cm−3, improving the conductivity of the solar cells; it also demonstrates a high defect tolerance nature when the defect density lies between 1E12 and 1E18 cm−3. After ZrS2 parameters optimization, the built‐in potential of SnS, Sb2Se3, Cu2SnS3, CuSb(S,Se)2, and Cu2BaSn(S,Se)4 solar cells is enhanced by 0.2, 0.58, 0.05, 0.42, and 0.3 V, respectively, reducing recombination rate. Upon optimizing absorbers parameters, a PCE > 35% for SnS, Sb2Se3, and CuSb(S,Se)2 while >32% for Cu2SnS3 and Cu2BaSn(S,Se)4 solar cells is accomplished with low VOC loss (≈0.1 V). The absorbers must have high carrier concentration (1E20 cm−3) and low defect density (1E14 cm−3) to achieve these PCEs.
