Structures based on porous silicon with single and double-layer coatings photoelectric properties

The spectral dependences of the reflection coefficient and the current-voltage characteristics of structures for solar cells based on porous silicon with single- and double-layer coatings from zinc sulphide and dysprosium fluoride are investigated. It is shown that solar cells based on double-layered structures have the highest conversion efficiency, which confirms the passivating properties of dysprosium fluoride on different types of working surface.
