Scientists from the Institute of Solar Energy of the Academy of Sciences of Turkmenistan for the first time created a photodetector of ultraviolet rays based on nanostructures, designed to measure the intensity and dose of ultraviolet rays emanating from the sun and lamps. The main feature of this photodetector from other previously used detectors is that it was first created on the basis of nanostructures of dielectric metal (oxide), which has the properties of a semiconductor (Au-Ga203 (Fe) -n-GaP). Sensitivity of the device is 2-3 times higher than previous analogues. The photodiode housing of the device consists of a gold layer (Au) 12-14 nm in thickness and an oxide (Ga203 (Fe)) with a thickness of 3-5 nm. Taking into account the low weight and high photosensitivity of the device, it can be widely used in various fields where it is necessary to measure the intensity of ultraviolet rays, including medicine, ecology, photobiology, biotechnology, astrophysics and space research. By measuring the intensity of ultraviolet rays emanating from the Sun at the resorts of Turkmenistan (Avaza, Bayramali, etc.), it is possible to study the effect of rays on the human body, identifying the most suitable season and time of the day for medical procedures in the open air. In addition, using a new photodetector, it is possible to measure the thickness of the ozone layer in the atmosphere and collect the necessary data on ozone "holes".Arslan KEMALOV
The results of studies of nanostructured semiconductors were published in the journal "Nanotechnika". published in Moscow, in summaries of international scientific forums held in the Turkmen capital, Novosibirsk, Moscow, Vienna, Odessa, Yekaterinburg and Tashkent.
The main conclusions and recommendations on the practical application of the development of Turkmen scientists were presented at the Turkmen-Chinese scientific forum dedicated to innovative technologies and their implementation (Ashgabat, 2017).
The Institute of Solar Energy is engaged in research of alternative energy sources (sun, wind) and their application in the national economy.
