[en] The paper presents an innovative way to improve the efficiency of solar energy. The requirements for the two components of the solar cell (the substrate material and the nature of the p-n junction) are determined. The necessity of nanotechnological preparation of the solar cell substrate is shown. The conditions under which technical silicon can be considered as a substrate are determined. A physical picture of the growth process of nanoclusters on the substrate surface based on the fundamental physical effect of self-organization of semiconductor systems is given. The least acceptable parameters of the nanocluster material are determined. The mechanism of the formation process of nanoheterogeneous structure is determined. The special role solar cell nanocomponents is revealed. (authors)
[en] Energy is the engine of development and prosperity. All countries need to secure sufficient energy to drive economic growth while working to mitigate the effects of climate change. Renewable sources of energy such as wind and solar power will play an important role in the future. At the same time, use of nuclear power will need to increase to provide the steady supply of baseload electricity. As one of the lowest-carbon technologies for generating electricity, nuclear power will also help countries meet their goals of reducing greenhouse gas emissions. This edition of the IAEA Bulletin, published for the International Ministerial Conference on Nuclear Power in the 21st Century, covers some of the most relevant topics on nuclear power and its role in contributing to sustainable development.
[en] In the present work the course of temperature air change is investigated at its presence essential fluctuation. In connection with that the greatest climate change has started since 60th years, has considered the question of course temperature air change for the period since 60 to 90 years on the West Pamir.

[en] Present article of book is devoted to spectres of Langmuir oscillations in a short-wave area. Using of spectres of modulation oscillations the spectres of Langmuir oscillations in the short-wave area have been found.
[en] Present article of book is devoted to spectres of modulation vibrations in a short-wave area. The equation of correlation functions of modulation perturbations in a short-wave area has been solved. It has been defined that spectres of modulation oscillations found allow to determine spectres of Langmuir oscillations in short-wave area.
