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.
