Abstract
In this research, the ZnSe/Ag/CdTe (ZAC) transparent conductive multilayer system was designed and simulated. The optimal thickness of the layers was determined to obtain high transmittance and low electrical resistance simultaneously. To investigate the optical properties of the multilayer system, the transmission spectrum, reflection, and effective energy band gap of the multilayer system were determined. The optimal thicknesses for the ZnSe, Ag, and CdTe layers were calculated to be 40 nm, 12 nm, and 35 nm, respectively. The results showed that the designed system can be used as an interlayer electrode in solar cells. For this purpose, a two-terminal tandem perovskite (CH3NH3PbI3) and silicon solar cell with the structure FTO/TiO2/Perovskite (CH3NH3PbI3)/Spiro-OMeTAD/ZAC/C-Si(n)/C-Si(p)/C-Si(p+)/Mo was simulated using SCAPS software. The values of open circuit voltage (Voc), current density (Jsc), fill factor (FF), and power conversion efficiency (PCE) were obtained as 1.62 V, 20.40 mA/cm2, 89.30%, and 29.51%, respectively. Generally, the results showed that the designed ZAC system has good potential for application in optoelectronic devices
