“…However, a promising member of the quaternary compound semiconductor group, Cu 2 MnSnS 4 is a cost-effective, environmentally benign, earth-favored compound, which possesses a tunable direct bandgap in the range from 1.49 to 1.51 eV and high coefficient of absorption in visible region (α ≥ 10 4 cm −1 ) [ 13 , [16] , [17] , [18] , [19] ]. The computational efficiency of 16.5–20.26% obtained in an i-ZnO/CdS/Cu 2 MnSnS 4 and ZnO:Al/i-ZnO/buffer (ZnO, ZnS, CdS)/CMTS heterostructure recently [ 6 , 20 ]. However, a detailed investigation of the CMTS-absorber layer with a favorable BSF layer, buffer layer, satisfactory metal contact, and consistency has been unexplored.…”

Emerging BaZrS3 and Ba(Zr,Ti)S3 Chalcogenide Perovskite Solar Cells: A Numerical Approach Toward Device Engineering and Unlocking Efficiency

“…Influence of Different ETL and HTL. We systematically examined 12 ETLs (Bi 2 S 3 , 51,52 ZrS 2 , 53,54 SnS 2 , 55 In 2 S 3 , 56 ZnS, 56 Zn 2 SnO 4 , 57 74 Cu 2 ZnSn 1−x Ge x S 4 74 ) to identify suitable transport layers for emerging BaZrS 3 chalcogenide perovskite devices (Figure 4) and their simulation parameters are given in Table S1. As previously discussed, we initially optimized SnO 2 (ETL), BaZrS 3 (absorber), and Cu 2 S (HTL) in our base device by varying the thickness, carrier concentration, and defect density.…”

“…However, these materials tend to be expensive and less stable. Interestingly, inorganic ETLs are a promising alternative due to their high stability, easy preparation process, cost-effectiveness, and excellent electronic properties. , Considering these advantages, we have carefully curated a list of 12 promising inorganic ETLs, including Bi 2 S 3 , , ZrS 2 , , SnS 2 , In 2 S 3 , ZnS, Zn 2 SnO 4 , BaSnO 3 , Al 2 O 3 , , WO 3 , TiO 2 , ZnO, and SnO 2 for our simulation. On the other hand, the choice of HTLs significantly affects the device’s performance, durability, and production cost.…”

Ab Initio Investigation for Solar Technology on the Optical and Electronic Properties of Double Perovskites Cs2AgBiX6(X=Cl, Br, I)

“…1 As a result, several investigations that combine theory and experiment have been conducted to better analyze and refine the phenomena of producing energy from the Sun. [2][3][4][5][6][7][8][9][10] Photovoltaic components like silicon, thin chalcopyrite films, and CdTe, are currently gaining interest because of their great optical characteristics and important conversion efficiency. The PV industry is presently largely based on silicon technology 11 because silicon is a long-studied and well-known compound, in particular, because of the development of microelectronics, it represents 25.7% of the Earth's crust.…”
