Abstract

In this paper, we consider the effect of porous silicon and dysprosium fluoride films on the current-voltage characteristics of low-dimensional photosensitive structures based on silicon. The processes of creating and studying the resulting photosensitive structures are described. The current-voltage characteristics of the structures before and after coating are given. The study found a positive effect of porous silicon and dysprosium fluoride coating on the current-voltage characteristics of structures both with and without porous silicon. Values of the optimal thickness of the dysprosium fluoride coating for porous photosensitive structures are obtained. It is shown that dysprosium fluoride coatings do not always have a positive effect on such parameters of photosensitive structures as short-circuit current and open-circuit voltage, since this is due to the non-uniformity of film deposition on the surface of the structure.
