Effect of Halide Ion in the Perovskite on Perovskite Solar Cell Performances

In this paper, a p-i-n perovskite solar cell was studied using Solar Cell Capacitance Simulator (SCAPS). A perovskite solar cell with MAPbI
3
and a perovskite solar cell with MAPbBr
3
as the light-absorbing materials have been simulated and compared the effect of the halide ion on solar cell performances. The efficiency of MAPbI
3
and MAPbBr
3
were reached 16.8% and 5.14% respectively. Also, the thickness of each MAPbI
3
and MAPbBr
3
was varied from
$0.1\ \mu\mathrm{m}$
to
$1.2\ \mu\mathrm{m}$
and the best results were observed at
$0.5\ \mu\mathrm{m}$
and
$0.4\ \mu\mathrm{m}$
thickness of MAPbI
3
and MAPbBr
3
films, respectively. A considerable effect of halide ions on perovskite solar cell performances can be attributed to the variation of light absorption with the halide ions.
