This paper reports the simulation and optimization of the perovskite-based photovoltaic solar cell. The basic perovskite solar cell simulated in this work is a planar n–i–p structure. It consists of three different layers: a perovskite absorbing layer, which is sandwiched between the electron-transport layer (ETL) and the hole-transport layer (HTL). The present paper shows numerical simulations of a planar heterojunction solar cell having the following structure: FTO/ETL/perovskite/HTL/Au (FTO—fluorine-doped tin oxide). Formamidinium lead triiodide (FAPbI3) is used as perovskite absorber material; intrinsic tin oxide (i-SnO2) and tungsten disulphide (WS2) are used as electron-transport layer, and cuprous oxide (Cu2O) and Spiro-OMeTAD are used as hole-transport layer. The effects of the ETL and HTL types and the thickness of each layer are given by means of simulation using SCAPS-1D software. The obtained results show that a cell with WS2 (50 nm), FAPbI3 (750 nm) and Cu2O (10 nm) gives better efficiency of 26.07%.
Key words: perovskite solar cells, SCAPS-1D simulation, electron-transport layer, cuprous oxide, tungsten disulphide, defects.
