“…In Figure 12c, V oc keeps almost constant as R s increases while J sc decreases continuously. The single diode equivalent current of the DPSC can interpret these trends ( Figure ), which can be described by the following equations: [ 108,122 ]

J = J_{normalL} - J_{normalD} - J_{normalP}

J = J_{normalL} - J_{0} (e^{\frac{q (V + J R_{normals})}{A K T}} - 1) - \frac{(V + J R_{normals})}{R_{sh}}

where J L is the photogenerated current, J D is the diode current, J P is the shunt current, J 0 is the reverse bias saturation current, A is the diode ideality factor, R s and R sh are the inherent series and shunt resistances in the cell. By bringing the open‐circuit condition ( V = V oc , J = 0) and the short‐circuit condition ( V = 0, J = J sc ) into Equation (), the following equations are obtained

J_{normalL} = J_{0} (e^{\frac{q V_{oc}}{AKT}} - 1) + \frac{V_{oc}}{R_{sh}}

J_{normalL} = J_{sc} + J_{0} (e^{\frac{q J_{sc} R_{normals}}{AKT}} - 1) + \frac{J_{sc} R_{normals}}{R_{sh}}

Research on organic-inorganic lead halide perovskite solar cells (PSCs) has developed rapidly in the last decade, with energy conversion efficiency (PCE) increasing from 3.8% in 2009 to 25.7% in 2022, [1][2][3] which is an unprecedented rate of development in the photovoltaic (PV) field. Owing to the superior properties of perovskite materials, such as suitable and tunable bandgap, long carrier diffusion length and lifetime, high optical absorption coefficient, high charge carrier mobility, and simple solution processing, PSCs have the potential to compete with the traditional crystalline silicon, CdTe, and organic solar cells in terms of both performance and cost. [2,4,5] Unfortunately, there are still two unresolved issues on the road to the actual commercialization of PSCs: one is the toxicity due to the presence of lead ions, and the other is the intrinsic instability due to the volatility of the organic components. [2,[6][7][8] To overcome the intrinsic instability of perovskite, an intuitive and valid approach is replacing the A-site organic cation (e.g., MA þ and FA þ ) in the traditional organic-inorganic perovskite ABX 3 with an inorganic cation (e.g., Cs þ ), which can increase the decomposition energy of perovskite and thus enhance the intrinsic stability. [9] To address the toxicity issue, the intuitive solution strategy is the substitution of Pb 2þ with divalent nontoxic metal ions (e.g., Sn 2þ and Ge 2þ ). [10][11][12] However, since Sn 2þ and Ge 2þ occupy high-energy 5s and 4s orbitals, they are easily oxidized in the air to form Sn 4þ and Ge 4þ . [13] Another strategy employs trivalent nontoxic metal ions (e.g., Bi 3þ and Sb 3þ ) to replace Pb 2þ , forming 0D or 2D layered perovskites with the formula Cs 3 M 2 X 9 (M = Bi 3þ , Sb 3þ ; X = I À , Br À , Cl À ). [14][15][16][17][18] Due to the isolated network of metal-halide octahedral units, these materials show undesirable optoelectronic properties, such as low carrier mobilities and indirect bandgaps. [17,18] Recently, a promising novel strategy has been proposed by replacing the B-site ions in the adjacent lattice of the traditional perovskite structure ABX 3 with a pair of heterovalent (i.e., monovalent and trivalent) nontoxic metal ions to form the double perovskite structure with the formula A

“…The proposed device can be described by a single‐diode equivalent circuit model, as shown in Figure 13c, and governed by Equation (9) and (10). [ 62,63 ] In this model, the diode current accounts for recombination losses in the bulk, while the second diode is neglected due to low recombination at both the absorber/ETL and HTL/absorber interfaces, as demonstrated in Figure 7b and 10b.

This article comprehensively investigates the photovoltaic performance of a 3% GeI2‐doped ASnI2Br absorber in a solar cell. The cell features an inverted structure (fluorine‐doped tin oxide [FTO]/poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate [PEDOT:PSS]/absorber/C60/Ag) and utilizes EDA0.01(GA0.06(FA0.8Cs0.2)0.94)0.98 as the A‐site cation (EDA for ethylenediamine; GA for guanidinium; FA for formamidinium). Through systematic numerical simulation and optimization, the photovoltaic performance of the solar cell is enhanced by sequentially optimizing several parameters: 1) absorber thickness and defect density, 2) conduction band offset at the ASnI2Br/C60 interface, doping of the electron‐transport layer (ETL), and its interface with the absorber, and 3) valence band offset at the PEDOT:PSS/ASnI2Br interface, and doping of the hole‐transport layer and its interface with the absorber. Additionally, the impact of series resistance (Rs) variation on device performance is investigated. Starting with an initial power conversion efficiency (PCE) of 4.86%, the systematic numerical optimization process elevates it to an impressive 18.55%. Furthermore, a final cell structure is proposed where C60 is replaced with indium‐doped tin oxide (ITO) as the ETL layer. This optimized FTO/PEDOT:PSS/absorber/ITO structure demonstrates a remarkable PCE of 18.68%. These findings hold significant promise for advancing tin‐perovskite solar cell technology.
