The idea of solar cells with a distributed heterojunction consists in spreading the donor-acceptor border on the entire volume of the active layer to improve the efficiency of dissociation of photogenerated excitons. This principle in terms of the model has been generalized for the case of betavoltaic elements that convert the energy of the radioactive beta decay into electricity. The distributed in volume radioisotope source in the form of microparticles has been considered. The efficiency of dissociation and recombination and the recombination probability of generated carriers have been calculated. It has been shown that the dependence of the device efficiency on the scale parameter of the impurity has the maximum, determining the optimal structure of the three-dimensional heterojunction.

The influence of many factors on the electronic transport in organic semiconductor systems in conditions of the time-spacing experiment has been studied. For estimating the influence on the photo current kinetics of such factors, as the density states, the morphology of the percolation regions, the existence of defect layers , the nonhomogeneity of electric field, etc., the efficient Monte-Carlo algorithm, based on the interpretation of transient current as a density of the generalized random recovery process, has been applied. The test calculations for some multilayer structures have been made.
