2.Device simulation and structure
In this work, a numerical simulation of a planar heterojunction Sn-PSC was made using SCAPS. FF, Voc, Jsc, PEC, and QE are obtainedfor this device. The working simulation software is based on 1D. These curves are used to calculate Jsc, Voc, FF, and PCE for this designed solar cell.In this software perovskitesolar cells could be designed withseveral layers, and the simulationsdone in both mode, In this present work which performed under 1.5G illumination in SCAPS1D design by the University of Gent, Belgium [5,17].
The Device constructs FTO/TiO2/FASnI3/CuO2/metal contact. In this cell structure, FASnI3 acts like light-collecting materials, sandwiched betweenthe ETL (TiO2) and HTL as CuO2. However, FTO is the front contact, and Ag, Au,Cu, Ptwere used as a metal contact.
