A SCAPS simulation investigation of non-toxic MAGeI3-on-Si tandem solar device utilizing monolithically integrated (2-T) and mechanically stacked (4-T) configurations

Design and optimization of four-terminal mechanically stacked and optically coupled silicon/perovskite tandem solar cells with over 28% efficiency

“…The architecture of the bottom cell is composed of a moderately doped p-type c-Si layer sandwiched between highly doped p-type (p + ) and n-type (n + ) Si layers. The input parameters of different layers are obtained from theoretical and experimental literatures, including our previous study [ 23 , [28] , [29] , [30] , [31] , [32] , [33] , [34] ], and presented in Table 1 . The interface defect layer (IDL) is assumed to consider interface recombination.…”

“…The thicknesses and doping concentrations of the top cells’ absorber are optimized for each configuration to improve performance. Although numerous studies have employed simulation programs for the modeling and optimization of silicon/perovskite TSCs [ [23] , [24] , [25] ]. The primary impetus of current research is the lack of previous research on tandem cells based on low-cost, solution-processed, stable, and highly efficient PSCs.…”

Machine Learning Approach to Delineate the Impact of Material Properties on Solar Cell Device Physics

“…From the results showcased in Figure , it is apparent that back contact metals with their corresponding work function values of above 4.9 eV will yield relatively consistent device performance. Popular back contact metals like silver yield a lower work function of 4.6 eV and thereby should be considered a poor choice for this device. , …”

Investigation of the effect of different factors on the performance of several perovskite solar cells: a simulation study by SCAPS

“…The parameters of perovskite materials are extracted from literature (Abdelaziz et al, 2020;Abnavi et al, 2021;Chen et al, 2016;Deepthi Jayan & Sebastian, 2021;Gélvez-Rueda et al, 2017;Kanoun et al, 2019;Karimi & Ghorashi, 2017;Karthick et al, 2020;Kumar et al, 2020;Patel, 2021;Raj et al, 2021;Sarker et al, 2021;Tao et al, 2019;Tara et al, 2021;Zhao et al, 2017) and listed in Table 1, and the parameters of FTO, ETL and HTL are listed in Table 2, while the defect density values at interfaces are listed in Table 3. The simulation was carried out under sunlight and the device illuminated from the ETL side by the AM1.5G spectrum (1000 W.m −2 ), and the ambient temperature was assumed to be 300 K. The PSC devices configuration and the energy levels for all used materials has been shown in Figure 1 and Figure 2.…”
