One-dimensional model of heterostructure photovoltaic element (PE) was represented in the frame of hydrodynamic approach. Various CdTe-CdS PE characteristics calculated with this model show a good coincidence with experiment and the results available by the standard program AMPS. Some peculiarities of current-voltage characteristics (CVC) were analyzed connected with parasitic Schottky barrier to p-layer of CdTe-CdS PE with thin CdTe region. This is important for the interpretation of measured PE CVC.

Key words: Photovoltaic element, one-dimensional model, p-n junction, Schottky barrier, finite difference method.
