Experimental Parameters Effect on the ITO/PEDOT:PSS/MAPbI 3 /PCBM/Ag Inverted Organic Perovskite Photovoltaic Solar Cell Efficiency

We present a new statistical study to optimize the manufacturing conditions of hybrid perovskite-based photovoltaic cells (ITO/PEDOT:PSS/CH 3 NH 3 PbI 3 /PCBM/Ag). The parameters were varied at three levels; high, medium, and low, i.e., the rotation speed of the spin coating, ω , to deposit the organic–inorganic perovskite (CH 3 NH 3 PbI 3 ) film, the concentration of the holes conductor polymer (PCBM), C , and the solvents, dimethyl sulfoxide, N , N -dimethylformamide, and diethyl-ether evaporation time, t . The best performing device obtained a J_SC of 19.04 mA/cm 2 , V_OC of 0.971 mV, with a fill factor, FF of 46.54
