UNIQUE OPPORTUNITY TO CREATE CHEAP BUT EFFECTIVE SILICON SOLAR CELLS Imamov E. Z., Jalalov T. A.,Muminov R. A., Rakhimov R. Kh. 8.2. <...> UNIQUE OPPORTUNITY TO CREATE CHEAP BUT EFFECTIVE SILICON SOLAR CELLS Imamov Erkin Zunnunovich, Dr., Professor of physics deportment TUIT, Professor. <...> Tashkent University of Information Technologies, e-mail: erkinimamov@mail.ru Jalalov Temur Asfandiyarovich, senior lecturer Tashkent University of Information Technologies, e-mail: tdjalalov@gmail.com Muminov Ramizulla Abdullaevich, Academician Uzbekistan Academy of sciences. <...> Proposed technological factors selection of material of nanocluster as well as an analysis of the growth of physics, dislocation less and nanoheterostructures stability on the substrate based on the fundamental effect of self-organization of semiconductors systems. <...> By using nanotechnology the negative properties of cheap and faulty silicon to transform into advantages. <...> Index terms: solar energy, solar cell, nanoinclusions, quantum dots, nanoscale contact structure, nanoscale «p-n junction», self-organization. <...> Modern solar power requires the development of innovative approaches to improve production efficiency of solar energy, without which it can not compete with hydrocarbon energy. <...> The main component of the solar power device is a silicon solar cell, the efficiency of which is determined by geographical factors, its geometric forms, as well as the properties of the contact, the contacting materials, current collecting electrodes, and many other factors. <...> The main component of a solar cell is occurring in the area of contact between two materials embedded electrostatic field, the characteristics of which largely determine the efficiency of the solar cell. <...> The main method is used as a solar cell substrate, if possible, and strictly pure crystalline silicon. <...> The main factor is not traditionally offered in the approach is the use of technical silicon as a solar cell substrate, which is not characterized by a high degree of purity and crystalline structure of the ideal. <...> The use of technical silicon could lead to a sharp reduction in price of the process of conversion of irradiative energy of the sun into electricity, as well as to an increase in the scope of application of solar energy capacity. <...> This is the uniqueness of the proposed solar cells with much of the defective technical silicon substrate. <...> There was nothing like it before, because it is <...>
