I am having much lower current density in mp-TiO perovskite devices comparing with the Al2O3 made ? What can I do?

Hi I am fabricating mp-TiO2 Perovskite solar cells (Glass/ftO/bl-TiO(50 nm)/mp-TiO/CH3NH3PbI3-XClx/Spiro/Au), but I am getting low current density (10 mA cm-2), Voc is 0.74 V and FF is 0.55. I was...
