This paper presents the results of a study on the creation of a combined film photothermoelectric converter from film photo- and thermal converters. The relevance of such research is substantiated. A list of questions necessary when solving scientific problems in this direction is provided. The importance of selecting materials and types of converters for obtaining effective hybrid elements is described. The limits of temperature intervals at which a positive result of experimentation of structures can be expected are shown. The calculation method and conditions for selecting the initial data for mathematical calculations of the characteristics of the converters are outlined. The results of the study are presented and the dependence of the electrophysical properties of the thermoelements and the efficiency of the converters on the temperature of the samples are analyzed. A conclusion is drawn about the possibility of creating such current sources. The issue of creating highly efficient solar energy converters has attracted the attention of researchers worldwide on a large scale.
