The electroconductivity, photoconductivity and relaxation curves of the nonequilibrium photoconductivity in InGaTe2 crystals under incandescent lamp light sources and laser light have been experimentally investigated. It is shown that the optical absorption in the InGaTe2 due to indirect and direct optical transitions, the band gap of 1.02 eV and 1.42 eV, respectively. Acceptor centers are found, at a depth of 0.203 eV and 0.801 eV. At high levels optical excitation in InGaTe2 observed two-photon absorption. It was found that the nonequilibrium photoconductivity observed in InGaTe2 crystals under the action of 1st and 2nd harmonic of neodymium laser radiation, due to the impurity, bipolar and the two-photon photoconductivity.
