By the first principles calculations and X-ray diffraction simulations, weperform a systematic study of multiple superconducting phases ofpotassium-doped picene [Nature {\bf464} 76, 2010]. The combination of optimizedlattice parameters, formation energy, and simulated X-ray diffraction spectraindicates that the superconducting phase with transition temperature (T$_c$) of7 K corresponds to a charge doped K$_2$picene, which is semiconducting with a0.1 eV energy gap, while the superconducting phase with T$_c$=18 K correspondsto a metallic K$_3$picene. The distinct crystal and electronic structures ofK$_2$picene and K$_3$picene provide a reasonable explanation of twosuperconducting phases in potassium-doped picene.
