A method of photoelectromotive force (PEMF) was developed to find the charge sign, mobility, and lifetime of photo charge carriers in ice generated by photons with energy hv>6.5 eV. It was determined that the most mobile photo charge carriers are negative ones, with mobility mu increasing from 2x10(-3) cm(2)/V s at T=-10 degrees C to 4x10(-2) cm(2)/V s at T=-30 degrees C, and with their lifetime decreasing from 30 to 10 s in ttemperature range. Activation energies of the mobility and the lifetime are E(mu)=-0.77 eV and E(tau)=0.32 eV, respectively. In addition to the negative photo charge carriers positive ones arise with mobility mu=2.3x10(-4) cm(2)/V s and lifetime tau=26 min at T=-15 degrees C. We suggest that the negative photo charge carriers in ice are mobile complexes of an electron, vacancy and D-defect (e(-) + V + D). To take into account a specific mechanism of charge transport in ice, configurational vector Omega, and the generation of complexes (e(-) + V + D), a reaction of "autoionization" was modified for ice, 2H(2)O + hv--> H3O+ + OHint.(e(-) + V + D).
