Оптимизация антиотражающего и пассивирующего слоя является наиболее экономичным способом увеличения КПД. В данной работе исследовано влияние предварительной очистки на пассивирующие свойства пленок диоксида кремния (SiO2), выращенных методом быстрого термического отжига (RTP) при температурах отжига 900 и 950 °С в атмосфере сухого кислорода. Выращивание тонких пленок SiO2 на поверхности монокристаллических пластин кремния осуществлено в камере французской установки быстрого термического отжига AS-ONE 150. Измерения бесконтактным СВЧ-методом времени жизни неосновных носителей заряда показали, что наилучшая пассивация образцов достигается при применении предварительной трехэтапной химической очистки (RCA) поверхности пластин кремния n-типа. Методом ИК-спектроскопии формирование слоя SiO2  подтверждается наличием интенсивного максимума при 1071 см-1, что было отнесено к валентным колебаниям типа «растяжение-сжатие». Результаты расчетов оптических констант полученных пленок SiO2  с использованием спектров отражения и программного обеспечения SCOUT показывают наличие слоя диоксида кремния, у которого показатель преломления и коэффициент экстинкции близки к эталонным. </p></abstract><trans-abstract xml:lang="en"><p>As it is known, increasing the efficiency of silicon solar cells is one of the most important tasks in modern alternative energy industry. Optimization of the antireflection and passivation layer is the most economical way to increase efficiency. In this work, the effect of pretreatment on the passivation properties of silicon dioxide (SiO2) films grown by rapid thermal processing (RTP) at annealing temperatures of 900 and 950°C in a dry oxygen atmosphere, was studied. The growth of thin films of SiO2  on the surface of monocrystalline silicon wafers was carried out in the AS-ONE 150 rapid thermal annealing chamber (France). Measurements of the lifetime of minority charge carriers by the non-contact microwave method showed that the best passivation of the samples is achieved by applying a preliminary three-stage chemical cleaning (RCA) of the surface of the n-type silicon wafers. IR spectroscopy confirmed the formation of a SiO2  layer by the presence of an intense maximum at 1071 cm-1, which was attributed to stretching vibrations of the "tensioncompression" type. The results of calculations of the optical constants of the obtained SiO2  films using the reflection spectra and the SCOUT software show the presence of a silicon dioxide whose refractive index and extinction coefficient are close to the reference.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кремний</kwd><kwd>диоксид кремния</kwd><kwd>пассивация</kwd><kwd>быстрый термический отжиг</kwd><kwd>RCA очистка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silicon</kwd><kwd>silicon dioxide</kwd><kwd>passivation</kwd><kwd>rapid thermal annealing</kwd><kwd>three-stage chemical purification</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nussupov K.K., Beisenkhanov N.B., Keiinbay S., Sultanov A.T.
