Now days i refer research article "From Nano- to Micrometer Scale: The Role of Anti solvent Treatment on High Performance Perovskite Solar Cells".

DOI: 10.1021/acs.chemmater.6b05353

Chem. Mater. 2017, 29, 3490−3498

I used trifluorotoluene,toluene and chlorobenzene as anti solvent as suggested above article.

But my current density  and FF  is very low compare to this article.current density 20(mA/cm2) and FF 50.45%. Due to low current density and FF my PCE=13.00%.

please give mi suggestions .
