Abstract

Interface engineering plays important role in the fabrication of tandem and perovskite-based solar cells. Recent experiments show that the interface effects are caused by the coupling of the electron bands and the pairing of surface contact geometry. In particular, it has been experimentally revealed that the transition from a planar to a rough interface improves many photoelectric parameters of the device. This means that the value of the fractal dimension of the interface may be key factor in device performance. It is possible to formulate two problems: firstly, the understanding on simple models why the electrical properties are improved with fractal interfaces, and, secondly, to discuss one of the most promising approaches in modern electronics, namely technology of radiation applications in the creation of rough interfaces.
