If I construct two PSCs 1)MAPbI3 and MAPbI3-yBry based on common configuration FTO/bl-TiO2/mp-TiO2/perovskite/Spiro-MEOTAD/Au, which one will give higher hysteresis? and why? Any reference(s)? Thanks!
Dear Muhamad,
welcome,
According to the study given in the attached link, hysteresis is more apparent with Bromine. This study found that the main cause of hysteresis in the I-V curve is due to the migration of the halide ions with polarization. The migration of the bromide ion is easier than the migration of iodide according to their investigations. So, the hysteresis will be more pounced in perovskite containing more Bromine.
For the study please follow the link:https://actu.epfl.ch/news/solving-hysteresis-in-perovskite-solar-cells/

Dear Muhammad,
I totally agree with Prof Zakry.
