Current characteristic curve of an illuminated solar cell was used to determine its reverse saturation current density (J0), ideality factor (n) and resistances, by using numerical diode simulation. High efficiency amorphous silicon, heterojunction crystalline Si(HIT), plastic and organic-inorganic halide perovskite solar cell shows n=3.27 for a-Si and n=2.14 for improved HIT cell as high and low n respectively, while the perovskite and plastic cells show n=2.56 and 2.57 respectively. The J0 of these cells remain within 7.1×10<SUP>-7</SUP> and 1.79×10<SUP>-8</SUP> A/㎠ for poorer HIT and improved perovskite solar cell respectively.
