摘要

A tandem solar cell is designed by combining bandgaps to yield efficient models. Additionally, it utilizes a wider spectrum of solar energy. In this simulation, the full perovskite tandem solar cell (PTSC) reflects a Dion–Jacobson (DJ) 2D layer PeDAMA2Pb3I10 absorber with wide bandgap energy (Eg) of 1.88 eV for its top cell and a narrow bandgap halide (NBH) having composition FA0.7MA0.3Pb0.5Sn0.5I3 with the numerical value of Eg is 1.22 eV for its bottom cell. Due to the efficient simulation technique of SCAPS-1D for modelling the solar cell characteristics and its parameters, it has been used for the purpose of this study. After which all the parameters are analyzed to achieve optimum level of efficiency of the cell. In this simulation different parameters such as open-circuit voltage (Voc) is 2.16 V; short-circuit current density (Jsc) is 20.70 mA/cm2; fill factor (FF) is 71.81%; and 32.11% of power conversion efficiency (PCE) in tandem structure is obtained by optimizing both cells due to minimal thermalization and transmission losses which gives better PCE, by carefully altering parameters such as absorber thickness and total defect density for both the cells. Hence, the value of the filtered spectrum and current matching graph values were subsequently analyzed. These prudent studies do the rounds to prove a strong possibility that the perovskite tandem model will increase solar cell efficiency.
