Analysis of eco-friendly tin-halide Cs2SnI6-based perovskite solar cell with all-inorganic charge selective layers

A Comprehensive Analysis of Eco‐Friendly Cs2SnI6 Based Tin Halide Perovskite Solar Cell through Device Modeling

“…The initial proposed structure has material parameters, which are listed in Table 2, layer defects in Table 3, and interfacial defects described in Table 4. All the essential parameters used in this theoretical study have been derived from existing literature as follows: FTO, [38] TiO 2 , [39] Cs 2 SnI 6 , [35,36,[40][41][42] and Cu 2 O. [43,44] Moreover the other material parameters used for ZnO, CdS, and P3HT in the simulation have been summarized in Table S1 of the Supporting Information.…”

“…[ 35 ] A solar cell utilizing the same architecture, at the same defect concentration was demonstrated to have an optimum V OC = 1.0 V, J SC = 25.93 mA cm −2 , FF = 29.57%, and η = 7.73%. [ 36 ] The discrepancies in theoretical results and experimental values should be tackled in order to gain an in‐depth understanding of the physics behind the operation of perovskite material based solar cells.…”

First‐Principle Density Functional Theory‐Derived Nonleaded KSn1−xGexI3‐Based Perovskite Solar Cells: A Theoretical Study

“…A summary of the input PV parameters of the structural materials: ETL, HTL, perovskite, and FTO. [10,58,95] Properties FTO SnO 2 KSnI 3 KSn 0.5 Ge 0.5 I 3…”

“…[96] The minimal absorber level defect, the greater HTL layer doping concentration, and the much higher V oc are all related to the enhanced efficiency of the cell. [10,95] 3.8. Thickness Optimization of HTL and ETL…”

“…The configuration of the cells is FTO/SnO 2 /KSnI 3 / Spiro-OMeTAD/Au, FTO/SnO 2 /KSn 0.5 Ge 0.5 I 3 /Spiro-OMeTAD/ Au, and FTO/SnO 2 /KGeI 3 /Spiro-OMeTAD/Au. Table 2 [10,58,95] encloses the PV characteristics of ETL, HTL, and perovskites, employed in device simulation. The first cell with 100% Sn (x = 0), FTO/SnO 2 /KSnI 3 /Spiro-OMeTAD/Au, demonstrated an efficiency of 8.23%.…”
