Optical Properties of GexSi1 – x Binary Compounds in Silicon

Abstract

The use of alternative and renewable sources of energy supply in energy supply around the world is attracting great and practical interest. The growing interest in them is caused by environmental considerations, on the one hand, and the limited nature of traditional hydrocarbon energy sources, on the other. A special place among alternative and renewable energy sources is occupied by photoelectric solar energy converters, the study of physics, which has become a separate scientific direction of photovoltaics. The development and creation of photocells based on silicon by binary compounds of germanium atoms Ge x Si 1–x in volume is also of particular interest to scientists and specialists. Since the production of silicon with binary compounds of silicon-germanium with certain electrical parameters and structure allows you to significantly expand the spectral region of the sensitivity of photodetectors and the efficiency of photocells based on such materials.
