This work is devoted to find an optimal mode of doublesided drift of lithium ions into monocrystalline silicon in order to obtain large sized Si(Li) p-i-n structured detectors of X-ray radiation. As it was shown in the work the proposed method of obtaining large sized Si(Li) p-i-n structured detectors helps to reduse the effect of impurity inhomogeneities in the initial silicon crystal to detectors' electro-physical characteristics.
